Hi,
I was able to debug this issue, but I don't have a solution for it.
Maybe someone can explain me, how it comes to so much client connections for NFSv4?
Counter Value
-------------------------------- --------------------------------
storePool_ByteLockAlloc 0
storePool_ByteLockMax 1024002
storePool_ClientAlloc 65356
storePool_ClientMax 102401
At this time, I have only seen 5 IPs, which have a lock on that node:
ssh xxx@192.168.1.99 "set d -c off; rows 0; vserver locks nfsv4 show -inst" | tee locks.txt | grep -i "client name" | sort | uniq -c |sort -n
1 Client Name: 0.0.0.0/192.168.29.11 tcp NULL 0
1 Client Name: Linux NFSv4.0 192.168.20.132
1 Client Name: Linux NFSv4.0 192.168.20.148
1 Client Name: Linux NFSv4.0 192.168.26.116
2 Client Name: Linux NFSv4.0 192.168.20.109
5 Client Name: Linux NFSv4.0 192.168.26.141
Do all these clients create several connections to that node? Maybe, one for every file they want to access?
I can't move that lif to another node, like the solution is stating. I think also, that it is not a bug of the software of the clients.
Clients are linux VMs with NFS kernel client...
Does maybe NFSv4.1 has more client connections available?
