Re: slowness on nfs server

Thank you for replies. I checked for duplicate ip's - no. For tuned's network-latency I'm not sure, it's a fast local LAN. I'm thinking about "nfs locks" but I know almost nothing about it...

slowness on nfs server

Hello, Centos 7.7, several kernels updates (now latest). Server is nfs server with 10-20 nfs clients. When user logs in through ssh and try to do something (examples: open file through nano, or cp file to other location), sometimes it is very slow, nano opens 1KB file about 2 minutes. etc. Top shows...

NFS server logs

Hi,
How/where can I get slightly more detailed nfs server logs ?
If I set debug by running "rpcdebug -m nfsd all" then /var/log/messages is overloaded by thousand messages.

By "xfs_repair helps" do you mean the problem is solved?
If not, can you mount the partition (in read-only mode) if you boot from a live CD?
If so, then you may make a copy of your data.
Yes, problem is solved using xfs_repair. I also thought about booting from live CD if it didn't.

Re: error while extending xfs partition

About go home I already know, and this is not an option.
I expanded from 50GB to 90GB, could be a problem that for some reason /dev/sda1 is a swap partition there ? (data on /dev/sda2).
P.S. I did "test expand" on another virtual machine and got same error…
P.P.S. xfs_repair helps

Re: nfs4 automatic mount problem

Hi, Yes, by "automatic mount" I mean, if I do "mount -a" by hand, all mounts are ok. NFS server is Ubuntu 14, and it supports nfs4, afaik. This is an example of manual mount, as you requested: #mount -v -t nfs 191.168.0.1:/data/nfs/data1 /nfs/data1 mount.nfs: timeout set for Tue Nov 28 10:56:45 2017...

nfs4 automatic mount problem

Hi, I'm having problem with nfs share automount on Centos nfs client. Seems to be default nfs mount trying to use nfs4, but failing. If explicitly set 'vers=3', mounts ok. I found very similar case in RedHat's bugzilla, it refers to bug 1428939, which is closed from public: https://bugzilla.redhat.c...
