NFS mount lockups since about a month ago
Hi,
I use NFS mount (defaults so V4) /home directories with a simple server
over Gigabit Ethernet all running Fedora33. This has been working fine
for 25+ years through various Fedora versions. However in the last month
or so all of the client computers are getting KDE GUI lockups every few
hours that last for around 40 secs. /home is not accessible during this
time and it feels/looks to be an NFS lockup issue. There are no "NFS
server no responding" or such like messages in either the servers or
clients /var/log/messages and the network communications seems fine.
1. Have there been some changes to NFS recently in the kernel ?
2. Any idea where to begin to try and debug this ?
