Hello,
I'm also trying to use FITRIM on a simple XFS partition on a spinning
magnetic hard drive (remember those). I haven't had much luck. I'm
doing this just to get used to the commands when using this against a
thinly provisioned disk. I have no idea if this should work in this
configuration.
On a Debian system with Linux 3.0.0-2-amd64 when I issue:
# fstrim /
I receive:
fstrim: /: FITRIM ioctl failed: Operation not supported
With an strace this looks like:
open("/", O_RDONLY) = 3
ioctl(3, 0xc0185879, 0x7fff4ea851b0) = -1 EOPNOTSUPP (Operation not
supported)
My fstrim is from util-linux-2.19.1-5
I'd be happy to try to diagnose this further if people are interested.
Any suggestions where I should start would be much appreciated.
