All t= hat was some time ago and currently I forgot details. I'm not sure that this is= sue still exists in 11.2-RELEASE but i think it is related to next one. 2) Recent one: "mount -u -o ro" was hanged for a few second and then wrote "mount: /path/to/mountpoint: Resource temporarily unavailable" Second attempt of "mount -u -o ro" resulted in deadlock in "suspwt" state= of mount program. A lot of processes was deadlocked in state "suspfs". Not sure which of them appeared first. There was no disk activity (in gstat) for remounted partition during this deadlock. --=20 You are receiving this mail because: You are the assignee for the bug.=
