Hi all,
Firstly, Please CC me into replies as I'm not subscribed to this list.
I'm trying to confirm that Fedora 18 has enabled trim for XFS filesystems. I
have added discard to the mount options in /etc/fstab - however I do not see
it when looking at the output of 'mount':
UUID=b95a7b45-d197-45c0-a7d6-c13f930a38b3 / xfs
defaults,discard 0 1
/dev/sda2 on / type xfs (rw,relatime,attr2,inode64,noquota)
fstrim shows that trim is at least enabled, but I am unable to confirm if it
is done in realtime, or I am required to run fstrim manually.
# fstrim -v /
/: 48919015424 bytes were trimmed
Can anyone share some insight into this?
IIRC you have to rebuild your initrd so it picks up the new fstab
mount options for /, the other options is you should be able to do
mount -o remount,discard /. Thanks,
Hi Josef,
This was the basis of my query - even after a remount with the discard
option, 'discard' still wasn't present in the options - as seen by the
mount line quoted above.
