Description

Flags passed to lctl subcommands in interactive are ignored after the first invocation. For example:

% lctl
lctl > get_param -n osc.knotfs-OST0037-osc-ffff8807eab68c00.cur_dirty_bytes
0
lctl > get_param -n osc.knotfs-OST0037-osc-ffff8807eab68c00.cur_dirty_bytes
osc.knotfs-OST0037-osc-ffff8807eab68c00.cur_dirty_bytes=0
lctl > get_param -n osc.knotfs-OST0037-osc-ffff8807eab68c00.cur_dirty_bytes
osc.knotfs-OST0037-osc-ffff8807eab68c00.cur_dirty_bytes=0
lctl >

Expected behavior would be identical output all three times

This might be a duplicate of ~~LU-6025~~, which was just fixed recently. The patch to fix it was http://review.whamcloud.com/13063 and landed to master for 2.7.0.

Even if that isn't the issue, it makes sense to use that patch to help narrow down if there is something else causing the problem.

Here is the back-ported patch for Lustre b2_5 branch: http://review.whamcloud.com/13893
I'm verifying whether it resolves the issue in this ticket or not.

Here is the test result with the above patch on Lustre b2_5 branch:

# lctl
lctl > get_param -n osc.lustre-OST0000-osc-ffff88007db75c00.cur_dirty_bytes
0
lctl > get_param -n osc.lustre-OST0000-osc-ffff88007db75c00.cur_dirty_bytes
0
lctl > get_param -n osc.lustre-OST0000-osc-ffff88007db75c00.cur_dirty_bytes
0
lctl >

The patch can resolve the issue.
