NFS issue after upgrade to linux-5.8.2-artix1-1

22 August 2020, 20:57:23

I upgraded system today, got new kernel 5.8.2-artix1-1 with this update and NFS (client) stopped working. Well, I don't get any error. When I try to mount remote disk, PC hangs completely and I have to hard reset it. I tried several times and everytime it's the same.
NFS worked for me without any issues today before the upgrade.
My server is running Artix with linux-5.7.12-artix1-1.
Anyone else struggling with the same issue?

ok, some fixes for nfs are in 5.8.3 now
can you please try linux-zen (which contains newest 5.8.3 patch from all our artix kernels)

Code: [Select]

pacman -S linux-zen

edit bootmanager (grub etc.) and restart computer

5.8.3 contains:
nfs: Fix getxattr kernel panic and memory overflow
nfs: ensure correct writeback errors are returned on close()
nfs: nfs_file_write() should check for writeback errors
NFS: Fix flexfiles read failover

I think that's could be fix your problem

does it contain support for jfs? My root is jfs formatted and I got error message that it's not supported by zen kernel

Code: [Select]

CONFIG_JFS_FS=m
CONFIG_JFS_POSIX_ACL=y
CONFIG_JFS_SECURITY=y
# CONFIG_JFS_DEBUG is not set
CONFIG_JFS_STATISTICS=y

exist no reason, why should be jfs not supported by linux-zen

I did update-grub again, rebooted and it worked fine. I am in the system now with linux-zen booted. NFS mounted and I am syncing files. Hopefully it's going to complete soon without any issues :-)
Thanks

oh my god. Yet another hard reboot needed. System completely hang when VirtualBox and Firefox were running and I tried to open up a pic in Ristretto.
Seems like 5.8 branch is far from being ready for production.
Have to check if older kernel is still available somewhere. I don't have confidence in 5.8 after few hours with it

I have no problems with 5.8.x.

and again (starting VBox and starting download from package archive).
I will let system fix my partitions and just try to download rock solid 5.7.xx kernel to see if it solves my problem (writing from another PC running OpenBSD).

In such case try to report bugs to upstream, or use older kernel (eg. lts) and wait.
