Spent so long troubleshooting a container and Veeam Agent issue just to find out it was a kernel issue....And here I was worried that power outage borked something...

Kernel was updated to version 5.15.0-102-generic. I can mount the shares without problems (mount -t cifs), but then, df for example tells me: df: /mnt: Resource temporarily unavailable. I'm able to list and browse all the files, but accessing them (even readonly) is very unstable. Sometimes it works and sometimes it just gives me i/o errors. Switching back to 5.15.0-101-generic or 5.15.0-100-generic solves the problem and everything works again as expected. Seems like some bug has been implemented in 5.15.0-102-generic... To reproduce the problem, I started a while loop on one server to write to some file on a specific mounted CIFS share and read it from another one root@<hostname1>:~# while true; do echo "$(date) hallo" >> /mnt/hallo.txt; sleep 1 ; done -bash: /mnt/hallo.txt: Input/output error -bash: /mnt/hallo.txt: Input/output error ^C root@<hostname2>:~$ tail -f /mnt/hallo.txt Tue Apr 9 04:10:52 PM CEST 2024 hallo Tue Apr 9 04:10:53 PM CEST 2024 hallo Tue Apr 9 04:10:54 PM CEST 2024 hallo Tue Apr 9 04:10:55 PM CEST 2024 hallo Tue Apr 9 04:10:56 PM CEST 2024 hallo Tue Apr 9 04:10:57 PM CEST 2024 hallo Tue Apr 9 04:10:58 PM CEST 2024 hallo Tue Apr 9 04:10:59 PM CEST 2024 hallo Tue Apr 9 04:11:00 PM CEST 2024 hallo Tue Apr 9 04:11:01 PM CEST 2024 hallo tail: cannot determine location of '/mnt/hallo.txt'. reverting to polling: Resource temporarily unavailable Tue Apr 9 04:11:04 PM CEST 2024 hallo Tue Apr 9 04:11:05 PM CEST 2024 hallo Tue Apr 9 04:11:06 PM CEST 2024 hallo Tue Apr 9 04:11:07 PM CEST 2024 hallo Tue Apr 9 04:11:08 PM CEST 2024 hallo Tue Apr 9 04:11:09 PM CEST 2024 hallo Tue Apr 9 04:11:10 PM CEST 2024 hallo While doing this, both servers tell me, the resource is unavailable root@<hostname1>:~# df -h /mnt df: /mnt: Resource temporarily unavailable root@<hostname2>:~$ df -h /mnt df: /mnt: Resource temporarily unavailable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2060780/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
