What happens when the NFS server is rebooted?
When the NFS server boots, the NFS client hangs hard as if the disk would not respond. When the server is up again, the NFS client continues as if the disk would have recovered. Unless the NFS server changes the file handle. A reboot must not alter the file handle.
Why does my NFS drive attach to my server?
This would ensure that if you try to access the NFS drive from the client and the server is up, then the NFS drive will attach. Perhaps you can tweak the timeo and retrans options of the NFS mounts to achieve the desired behavior. See the nfs man page for more information.
When to see a ” stale NFS handle “?
You must not see a “Stale NFS handle”. Typically a NFS handle consists of the file system’s superblock and device path. It changes only when the filesystem is recreated or if its device path (/dev/something) is changed. I’m still dealing with issues on my local LAN that pertain to NFS.
What happens during client recovery in NFS Version 4?
During the recovery process, the client sends the server information about the client’s previous state. Note, however, that during this period the client does not send any new requests to the server. Any new requests to open files or set file locks must wait for the server to complete its recovery period before proceeding.
When to use reclaim _ complete in NFSv4?
If all NFS clients send RECLAIM_COMPLETE, the server does not delay to respond. NFSv4.1 RFC says, A RECLAIM_COMPLETE operation is used to indicate that the client has reclaimed all of the locking tate that it will recover, when it is recovering state due to either a server restart or the transfer of a file system to another server.
Why do I get stale NFS file handle?
Restart any desired processes. Note, if you run a cluster server setup you will get a stale nfs file handle every time the server must fail over. To avoid that you should export your file systems using the fsid option. The number for the fsid should be the same for each respective file system on the two servers.
Why is my NFS client impossible to remount?
So, when I use utp and then plug it out and connect to the wifi network, the nfs partitions become inaccessible and also impossible to remount. When I issue mount command, it just hangs there. If I reboot the laptop it mounts nfs without any problems. I have no idea why the reboot is needed but it fixes it.
We have an NFS 4 share, sharing a volume between a number of servers (NFS server, and clients all Debian 8). We have had some issues recently where network outages would freeze the client systems.
