Hello,
I seem to get intermittent systemd time out errors when trying to mount btrfs, which throws the system into systemd rescue mode.
e.g. "Job dev-sdb1.device/start timed out."
I can't actually see any reason for the problems in the systemd journal.
Furthermore, "mount -a" from rescue mode works perfectly.
Maybe the hard disks just aren't "waking up" fast enough in the boot sequence. I have reported slowness here before when system is cold, which I suspect is hard disk related (spinning WD disks). Hmm. It is now booting fine again, maybe I need to leave the hard disks on for a while before they start working properly...
smartctl reports nothing abnormal.
Any ideas?
Maybe time to get new hard disks?
I had that happen occasionally, but in my case when btrfs failed to mount it was because the disk never started up at all, and it was always the same disk. Are the disks in question spun up by the BIOS, or by Linux? Is it always the same disk, or a different disk each time? James
