I had a system crash this morning when I/O on a pool was hung with failmode=panic.
That was 7 1/2 hours ago and it's at 64%. I'm going to let it complete so the failure can be analyzed more, but I really need to find a way to significantly speed up the crash dumps. This system has 256GB ram and a dedicated dump pool of two 320GB mirrored SATA disks. I'm aware of the multi-threaded dump issue so I have these to lines in /etc/system set dump_plat_mincpu=0 set dump_bzip2_level=1 It's not clear where the bottleneck is. I don't think it's the disk. The disk activity lights are a light flicker, by no means being hit hard. Unless it's a serial latency issue. What would be my best approach to get good dumps from a system like this in minutes, not hours? Assuming that is possible.
