After some debugging I figured out, there are files on the filesystem that cause the accessing processing to hang. Even a simple ls or find can stuck if tries to access the file for some meta data. I still don't know if it's a coincidence or not, but all files were some kind of browser cache objects (browser, slack client, teams client).
I copied everything to a new ZFS dataset and set it to my home folder. It worked like charm for 2 weeks. So I think it cannot be a HW failure or must be something a very weird bug... Now I created a new ZFS encrypted filesystem and migrated my home folder to it again. If it starts failing again, it would confirm that problem occurs only if encryption is enabled. It's also worth mentioning, if I try to copy the zfs filesystem with zfs send, the machine gets locked up really soon. Even if it's caused by an HW eror, this must be a ZFS bug IMO. zfs scrub does not find anything. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1912188 Title: Load growing continously Status in zfs-ubuntu: New Status in linux package in Ubuntu: Confirmed Bug description: Recently load started growing with no end.
