Hi, we are facing an issue where we can't figure out if its XFS software related, or actually related to hardware, and can't quite figure out why we are facing the issues, though is doesn't seem hardware related. The issue is with a 102Tb array on a Dell branded LSISAS 3508 (Perc H840). Running Ubuntu with a 4.15.0-32 (Ubuntu branded), but we have also been running a number of 4.4.0-x with the same issues. The XFS filsusyem is on a very busy NFS server, and when the issue occurs we see strange issues with NFS, while the system seems healthy on the local server, but at the same time some programs are having problems accessing the fs. It occure roughly every 14 days, where we have to restart the fs to come back fully working. Sometimes refusing to unmount cleanly during shutdown, forcing us to fsck the fs on startup. It looks like its hanging in xlog_grant_head_wait, but I don't know enough to determine what can make it hang there. Hoping someone in here could have a look and point me in the right direction. Below is a trace from the last crash we had: Sep 9 23:23:51 ged kernel: [1436769.178935] INFO: task mysqld:2847 blocked for more than 120 seconds.
