Could you please advise on this one?

I don't think it's related to the SELinux on client.

The output shows some unconnected inodes.

'..' in ... (253) is /O/200000005/d2 (251), should be <The NULL inode> (0).
Fix? no

One thing confused me is that where the directory "/O/200000005" come from? "200000005" is seq FID_SEQ_QUOTA. Di/Fanyong, will DNE or lfsck create this directory? Thanks.

Hi, Saurabh

Is the system newly formatted or upgraded from old one? What kind of test did you run before the sanity? Have you ever run lfsck test?

[Saurabh Tandan (Inactive)]

Hi Niu,

The system for newly formatted to latest Tag 2.7.64 and I ran a group of tests and one of them was sanity.sh. The sequence of group was as follows : runtest, fsx, sanityn, replay-single, recovery-small, replay-ost-single, insanity, sanity-quota, sanity.sh . And no , I never ran lfsck test on it.

Hit the same issue when running sanity (sanity only) with 2.7.1 client and master server(tag-2.7.64) under DNE mode

is this a dup of LU-7116?

[Niu Yawei (Inactive)]

Yes, very likely.

Dup of LU-7116.
