whoops, sent from wrong email address, form right address now:
Hello,
I am using Lustre 2.4.2 and have an OST that doesn't seem to be written to.
When I check the MDS with 'lctl dl' I do not see that OST in the list.
However when I check the OSS that OST belongs to I can see it is mounted
and up;
0 UP osd-zfs l2-OST0003-osd l2-OST0003-osd_UUID 5
3 UP obdfilter l2-OST0003 l2-OST0003_UUID 5
4 UP lwp l2-MDT0000-lwp-OST0003 l2-MDT0000-lwp-OST0003_UUID 5
Since it isn't written to (the MDS doesn't seem to know about it, I
created a directory. The index of that OST is 3 so I did a "lfs
setstripe -i 3 -c 1 /mnt/l2-lustre/test-37" to force stuff that is
written in that directory to be written on OST03
However when I issue that command I get:
-bash-4.1# lfs setstripe -i 3 -c 1 /mnt/l2-lustre/test-37
error on ioctl 0x4008669a for '/mnt/l2-lustre/test-37' (3): Invalid argument
error: setstripe: create stripe file '/mnt/l2-lustre/test-37' failed
any ideas?
thanks!
Ron
