Document Version Release Date Details 3 June 21, 2022 Updated the drive model part numbers table in the Scope section to change from an image to text. 2 May 06, 2022 Updated the Scope with the part numbers for the drive models. 1 March 28, 2022 Original Document Release. The "fstrim" command in Linux is used to discard (or "trim") blocks that are not in use by the filesystem. Using the fstrim command for systems with the Solid State Drive (SSD) models listed in the Scope (below) can prevent the discard process from completing and an I/O error to display: fstrim: /mnt/mytest: FITRIM ioctl failed: Input/output error The issue occurs because these drives contain a threshold on the number of blocks to unmap. When fstrim passes that threshold, the fstrim process fails with the I/O error.

The SSDs are functioning according to design to ensure SSD health and performance. The drives contain a threshold on the number of blocks to unmap. When SSD passes its threshold, the fstrim process fails with the I/O error. To avoid the I/O error, limit the frequency that the fstrim command is run on the SSDs. Ensure the number of blocks specified to unmap is less than or equal to 0x100000 for the drives' sector size.
