Public bug reported:
If I run sudo fstrim -av I see:
/media/SSD_Data: 2 GiB (2145820672 bytes) trimmed
fstrim: /media/Win7: FITRIM ioctl failed: Bad file descriptor
/: 26.9 GiB (28823887872 bytes) trimmed
/media/SSD_Data is read-write mounted NTFS via ntfs-3g, and /media/Win7 is
read-only mounted NTFS, also via ntfs-3g. Lines from fstab:
UUID=censored /media/SSD_Data ntfs-3g
rw,noatime,nofail,big_writes,windows_names,nosuid,nodev,allow_other,hide_hid_files,inherit,noexec
0 0
UUID=censored /media/Win7 ntfs-3g
ro,nofail,big_writes,windows_names,nosuid,nodev,allow_other,noexec,hide_hid_files
0 0
If I do sudo umount /media/Win7 and then sudo mount -o rw /media/Win7
then sudo fstrim -av takes longer and succeeds for all filesystems. So,
it seems the read only is the problem.
This seems cosmetic, but it causes periodic runs of fstrim via systemd
to report failures.
