| # Ensure that we can't call fstrim on filesystems mounted norecovery, because |
| # FSTRIM implementations use free space metadata to drive the discard requests |
| # and we told the filesystem not to make sure the metadata are up to date. |
| # |
| # The following patches fixed the bug on ext4, xfs and btrfs |
| # ext4: prohibit fstrim in norecovery mode |
| # xfs: prohibit fstrim in norecovery mode |
| # Btrfs: do not allow trimming when a fs is mounted with the nologreplay option |
