Hello *
Will fstrim operations for a thin provisioning storage and xfs quota
conflict with each other ?
If i understand fstrim code correctly, in case of xfs / thin
provisioning storage it tells xfs to release unused blocks.
I have read indications that blocks are marked to the underlying storage
as freed by zeroing them out.
Is the "write zeros" correct information, or will be commands like scsi
unmap or FITRIM be sent to the storage ?
I found many exact references to fstrim on SSD, but no technical
description on which operation is implemented for thin provisioning
storages.
TIA
Micha
