I have a hyper-converged cluster running oVirt 4.4.10 and Gluster 8.6. Periodically, one brick of one volume will drop out, but it's seemingly random as to which volume and brick is affected. All I see in the brick log is: [2022-03-19 13:27:36.360727] W [MSGID: 113075] [posix-helpers.c:2135:posix_fs_health_check] 0-vmstore-posix: aio_read_cmp_buf() on /gluster_bricks/vmstore/vmstore/.glusterfs/health_check returned ret is -1 error is Structure needs cleaning [2022-03-19 13:27:36.361160] M [MSGID: 113075] [posix-helpers.c:2214:posix_health_check_thread_proc] 0-vmstore-posix: health-check failed, going down [2022-03-19 13:27:36.361395] M [MSGID: 113075] [posix-helpers.c:2232:posix_health_check_thread_proc] 0-vmstore-posix: still alive! -> SIGTERM Searching around, I see references to similar issues, but no real solutions. I see a suggestion that changing the health-check-interval from 10 to 30 seconds helps, but it looks like 30 seconds is the default with this version of Gluster (and I don't see it explicitly set for any of my volumes). While "Structure needs cleaning" appears to be an XFS filesystem error, I don't see any XFS errors from the kernel. This is a low I/O cluster - the storage network is on two 10 gig switches with a two-port LAG to each server, but typically is only seeing a few tens of megabits per second. -- Chris Adams <cma(a)cmadams.net&gt;
