Hi,
I'm experiencing a serious problem with XFS on 2.6.12-1.1376_FC3smp
The filesystem locks up (no write possible, mysql won't shut down, impossible to reboot machine from console) while running MySQL under a high load. The only error messages I can find are:
thales kernel: allocation failed: out of vmalloc space - use vmalloc=<size> to increase size. thales kernel: XFS: possible memory allocation deadlock in kmem_alloc (mode:0x250
I've tried increasing /proc/sys/vm/min_free_kbytes to 16386 without success.
Any ideas? Where should I start looking, what logs, programs/tests can i run?
The problem does not appear immediately, the shortest time from reboot to failure has been 4 hours.
Machine config: Dell 6650 / 4 x P4 Xeon with 12GB ram. 1.5T SCSI disk array / PW220S / Perc 4/DC running XFS on top of LVM. -- Sincerely, Joakim Tysseng - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
