FSTab discard, ssd & LVM-thin by veehexx » Wed May 20, 2020 1:08 pm i think we all know by now SSD/nvme needs discard/trim to clear out the old used blocks upon file deletions, which i've just found out LVM-thin provisioned disks also need the same (not used thin provisioned upto now) The fstab(5) file can be used to define how disk partitions, various other block devices, or remote filesystems should be mounted into the filesystem. Each filesystem is described in a separate line. These definitions will be converted into systemd mount units dynamically at boot, and when the configuration of the system manager is reloaded

FSTab discard, ssd & LVM-thin - CentO

  1. I have TF700 running Crombi-KK F2FS on data, and added the 'discard' flag to fstab.cardhu to (hopefully) ensure trim of flash memory. Is there some way to verify that the discard function is working
  2. discard/nodiscard Controls whether ext4 should issue discard/TRIM commands to the underlying block device when blocks are freed.This is useful for SSD devices and sparse/thinly -provisioned LUNs, but it is off by default until sufficient testing has been done. Means: TRIM feature from ssds. Take your time to read on this guy, and probe if your ssd support this feature(pretty much all modern ssds suport it)
  3. $ sudo /usr/sbin/fstrim --fstab --verbose --dry-run This will simply show what the fstrim command will do based on the file systems that it finds configured in your /etc/fstab file. $ sudo /usr/sbin/fstrim --fstab --verbose This will now send the TRIM operation to the drive and report on the number of discarded bytes from each file system
  4. The fstab file allows you to specify how and what options need to be used for mounting a particular device or partition, so that it will be using that options every time you mount it. This file is read each time when the system is booted and the specified filesystem is mounted accordingly. You could also comment out the specified lines and can manually mount filesystem after reboot

How to verify 'discard' flag working in fstab

  1. The fstab (/etc/fstab) (or file systems table) file is a system configuration file on Debian systems. The fstab file typically lists all available disks and disk partitions, and indicates how they are to be initialized or otherwise integrated into the overall system's file system
  2. Adding a new hard drive or solid-state drive to your Linux computer? You'll need to edit your fstab file. A lot of people find the very idea scary. Yes, it's critical that you get it right, but armed with the right knowledge, it really isn't difficult. We step you through the process of editing your fstab file to integrate your new drive into your file system
  3. If no policy is selected, the default behavior is to enable both discard types. The /etc/fstab mount options discard, discard=once, or discard=pages may also be used to enable discard flags. -e, --ifexists Silently skip devices that do not exist
  4. Edit /etc/fstab, enter: # vi /etc/fstab The syntax is as follows to mount btrfs device using UUID at /data/ mount point: UUID=e5b5c118-fb56-4fad-a45d-ff5fad9a649d /data btrfs defaults 0 0. Save and close the file. There you have it, an entry is added to /etc/fstab so the new disk will be mounted automatically at system startup
  5. Its true Delete discard from the /etc/fstab file Enable fstrim.timer (sudo systemctl enable fstrime.timer), Start fstrim.timer (sudo systemctl start fstrim.timer), Find out if the order has been correctly answered (sudo systemctl status fstrim.timer). It is true that the fstab file is to handle with extreme precaution. I use an Mate flavour. Regards, A Monkey In Winter. 2 Likes. tbg 9.
  6. Realtime discard is selected by adding the filesystem option discard while mounting. This can be done by the following examples: placing discard in your /etc/fstab for the filesystem: /dev/sda1 /mountpoint xfs defaults,discard 0 1; mount options: mount -o discard /dev/sda1 /mountpoint; Batch Mode . This mode requires user intervention. This intervention is in the form of the command fstrim. It.

Ich habe mir eine SSd in meinen Labtop gebaut und alles neu installiert. Anschließend habe ich die fstab Einträge geändert, so wie das in der Linux Welt beschrieben ist. Ich weiß nur nicht, ob die Einträge so korrekt sind, oder ob ich da noch was ändern muß. Für Tipps wäre ich dankbar. fstab: # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that.

Hier bekommt die SSD in der Datei /etc/fstab neben dem noatime von Punkt 8 oben auch noch ein discard verpasst.

Weitere Optionen können durch Kommas getrennt hinter oder zwischen dem markierten Teil eingebracht werden, wie im folgenden Beispiel: In einer nachbearteiten /etc/fstab aufgezeigt, die. During installation, the discard option is added to the fstab file. However, this option is deprecated, especially by RedHat, because it trim continues the file system, adding workload to it, this is the opposite of the desired effect. SystemD manages the trim with the fstrim.timer Re: SSD discard in fstab or fstrim from command line run 'fstrim -v /' (for the root file system) from crontab. This page should give you an idea for how to do it Online discard operations are specified at mount time, either with the -o discard option as part of a mount command or with the discard option in the /etc/fstab file. They run in real time without user intervention. Online discard operations only discard blocks that are transitioning from used to free. Both operation types are supported for use.

Alternatively if you're using dm-crypt, edit /etc/crypttab and make sure the discard option is there. Finally, you need to enable discard for all of your ext4 partitions: simply add the discard option to /etc/fstab. Note that swap on a swap partition will perform discard automatically. Please see the excellent SSD Optimization article for. As you might see, the /boot partition is probably mounted with the discard option, but / isn't. noatime is also ignored. Same filesystem, same mount options in fstab. Maybe the kernel don't remount / after getting access to it. So I tried to remount /, but it only use the noatime, discard still be ignored The fstab file allows you to specify how and what options need to be used for mounting a particular device or partition, so that it will be using that options every time you mount it. This file is read each time when the system is booted and the specified filesystem is mounted accordingly. You could also comment out the specified lines and can manually mount filesystem after reboot. As an. DESCRIPTION top. fstrim is used on a mounted filesystem to discard (or trim) blocks which are not in use by the filesystem. This is useful for solid-state drives (SSDs) and thinly-provisioned storage. By default, fstrim will discard all unused blocks in the filesystem [/donotprint]The file /etc/fstab contains descriptive information about the various file system on a Linux or Unix-like system. It is the duty of the system administrator to properly create and maintain this file. This is also useful if you don't have an initrd or your initrd does not scan for a btrfs device on boot. In this tutorial you will learn how to mount a btrfs device using /etc/fstab

Manually run an fstrim to discard all the currently unused crufty storage you've collected on all applicable filesystems: sudo fstrim -a Going forward, you can either add 'discard' to the mount options in fstab, or use fstrim periodically Batch discard operations are run explicitly by the user with the fstrim command. This command discards all unused blocks in a file system that match the user's criteria. Both operation types are supported for use with ext4 file systems as of Red Hat Enterprise Linux 6.2 and later, so long as the block device underlying the file system supports physical discard operations. This is also the case with XFS file systems as of Red Hat Enterprise Linux 6.4 and later. Physical discard operations are.

Extend the life of your SSD drive with fstrim Opensource

If it is not necessary to immediately discard freed blocks, then the fstrim tool can be used to discard all free blocks in a batch. Scheduling a TRIM during a period of low system activity will prevent latent interference with the performance of other operations. Also, a device may ignore the TRIM command if the range is too small, so running a batch discard has a greater probability of actually discarding the blocks Online discard from Kernel 2.6.33. The -o discard mount option (for example mount -o discard /dev/sdb1 /mnt/. For permanent activation, the option must be entered in /etc/fstab, because the discard capability is deactivated by default) Batched discard from Kernel 2.6.37; Accelerated batched discard from Kernel 3. Fstab is your operating system's file system table. If you want a review of file systems, be sure to check out our other article, HTG Explains: Which Linux File System Should You Choose? In the old days, it was the primary way that the system mounted files automatically. Nowadays, you can plug in a USB drive of any kind and it'll just pop up in Nautilus like it does in Windows and Mac OS. Alternatively, and often not recommended: Set discard mount option in /etc/fstab for the ext4 filesystem, swap partition, Btrfs, etc. See mount(8). See mount(8). The discard options is not needed if your SSD has enough overprovisioning (spare space) or you leave (unpartitioned) free space on the SSD

The /etc/fstab mount options discard, discard=once, or discard=pages may also be used to enable discard flags. -e, --ifexists Silently skip devices that do not exist. The /etc/fstab mount option nofail may also be used to skip non-existing device Um die TRIM-Funktion zu aktivieren, fügen wir der fstab die Mount-Option discard hinzu. Eine weitere Optimierung ist, die letzte Zugriffszeit auf eine Datei nicht mitzuprotokollieren. Dies ist zum einen nicht unbedingt nötig, und macht die SSD auch unnötig langsamer. Um dies zu erreichen, fügen wir die Option noatime hinzu. Die fstab-Datei öffnen wir so: sudo nano /etc/fstab. Ich habe jetzt mal mit eingeschalteten online-discard ein fstrim -v / und ein fstrim -v /home laufen lassen. Das war vor nicht mal einer Woche (6.01) Es wurden angeblich hohe GB-Zahlen getrimmt. jeweils deutlich mehr als die Hälfte der Partition. heute habe ich fstrim wieder über die zwei Dateisysteme laufen lassen.

Setup and force TRIM in fstab with the following options in your /etc/fstab discard, noatime and commit=500 (Note: if you are concerned with possible data loss with commit, set it lower) #> vi /etc/fstab fat und ntfs kennen keine Unix-Dateirechte. Da darf jeder alles. Um das einzuschränken hast du bisher Rechte in der fstab (als User- bzw. umask-Option) mitgegeben, die dann das Betriebssystem (nicht das Dateisystem) anwendet. Die ext-Dateisysteme kennen Unix-Dateirechte und auf dieser Ebene passiert hier auch die Rechtevergabe. Daher brauchst du in der fstab keine umask und musst einzelnen Dateien nach dem Erstellen des Dateisystems (durch root - daher der Eigentümer) vom Standard. On the other hand, if you were using the discard-at-fstab option you wouldn't have any chance of recovering the file, because the OS would have told the SSD to TRIM that blocks as soon as you deleted the file, and consequently the SSD has irreversibly destroyed such blocks. Here you have simple script to run fstrim on the /, /boot and /home partitions, which can be programmed to be executed. If no policy is selected, the default behavior is to enable both discard types. The /etc/fstab mount options discard, discard=once, or discard=pages may also be used to enable discard flags.-e,--ifexists Silently skip devices that do not exist.

Editing the fstab File. Open the fstab file in an editor. We're using gedit, an easy to use editor found in most Linux distributions. sudo gedit /etc/fstab. The editor appears with your fstab file loaded in it. This fstab file has two entries already in it For NFS file system mounts, a line in the /etc/fstab file specifies the server name, the path name of the exported server directory to mount, the local directory that is the mount point, the type of file system that is being mounted, and a list of mount options that control the way the filesystem is mounted and how the NFS client behaves when accessing files on this mount point. The fifth and sixth fields on each line are not used by NFS, thus conventionally each contain the digit zero. For. An entry ignore causes the line to be ignored. This is useful to show disk partitions which are currently unused. An entry none is useful for bind or move mounts. See also the previous section in man fstab, The second field that also mentions the use of none. - Jonathan Ben-Avraham Aug 7 '16 at 5:3
