Thank you.So may be unlink the rebalance pid file leads to xfs shutdown.I repair xfs and in lost+foud I find the inode:the inode is lead to xfs shutdown isAfter xfs shutdown I got the following log:/var/log/secure indicates I start rebalance on Apr 15 11:58:11See logs bellow:Glusterfs try to unlink the rebalance pid file after complete and may be this is where the issue happens.glusterfsd/src/glusterfsd.c line 1332 there's an unlink operation.In glusterfs3.3And I got some more info and hope you're interested.Hi Eric,I'm sorry for spaming.
if (ctx->cmd_args.pid_file) {
unlink (ctx->cmd_args.pid_file);
ctx->cmd_args.pid_file = NULL;
}

Going forward, could I ask that you take a few minutes to batch up the information, rather than sending several emails in a row? It makes it much harder to collect the information when it's spread across so many emails.
