Subject: tests/bugs/tier/bug-1286974.t failed and dropped a core
Hi guys,
could you please have a look at this regression test failure?
Pranith, could you or someone with EC expertise help us diagnose this problem?
The test script does:
TEST touch /mnt/glusterfs/0/file{1..100};
I see some number of errors such as:
[2016-01-12 20:14:26.888412] E [MSGID: 122063] [ec-common.c:943:ec_prepare_update_cbk] 0-patchy-disperse-0: Unable to get size xattr [No such file or directory]
[2016-01-12 20:14:26.888493] E [MSGID: 109031] [dht-linkfile.c:301:dht_linkfile_setattr_cbk] 0-patchy-tier-dht: Failed to set attr uid/gid on /file28 :<gfid:00000000-0000-0000-
0000-000000000000> [No such file or directory]
.. right before the crash. The backtrace is in mnt-glusterfs-0.log, it failed in ec function ec_manager_setattr().
It appears to be an assert, if I found the code right.
GF_ASSERT(ec_get_inode_size(fop,
fop->locks[0].lock->loc.inode,
&cbk->iatt[0].ia_size));

This is because dht sents setattr on an inode that is not linked. For
now we are addressing it in EC with http://review.gluster.com/13039.
Regressions need to pass.
