Hello, when copying 10GB of files (from/to XFS on LVM on LUKS on RAID), system hung and did not recover for >1 hour. Other file access hung too. Had to REISUB. Some file corruption afterwards. Is this a known issue? It only happened once, so far I am unable to reproduce it. Kind regards Johann ------------ Oct 11 15:15:43 kernel: INFO: task cp:9636 blocked for more than 122 seconds.
