System was not absolutely frozen but even ssh login took a 30 sec before succeeded. Executing anything from shell was taking a long delay before able to run. The "top" command reveled 100% CPU utilization on btrfs-cleaner kernel thread. I was able eventually run "btrfs quota disable /" and system started to be responsive again after a while. It was in the middle of the day and as a database server running MariaDB and PostgreSQL it is not acceptable for the server to stop responding and do some btfrs cleanup even for few seconds nor 15 minutes IMHO. Server: Leap15.2 up to date, 32GB RAM, SSD 512GB, 2x8core XEON, FS 20% full We are using timeline and number snapshots on /backups subvolume and number snapshost (created by zypper) on / Is there any way I can help to resolve this issue? -- You are receiving this mail because: You are on the CC list for the bug.
