Hello, this may not apply to your machine. I have two changes to your setup: * Opensolaris instead of Nexenta * DL585G1 instead of your DL380G4
Here's my problem: reproducible crash after a certain time (1:30h in my case). Explanation: the HP machine has enterprise features (ECC RAM) and performs scrubbing of the RAM, just as you could scrub ZFS disks; with the 4 AMD dual core CPUs, the memory is divided into 4 chunks and when the scrubber hits a hole, then the machine crashes without so much as a crashdump Solution: add the following to /etc/system set snooping=1 set pcplusmp:apic_panic_on_nmi=1 set cpu_ms.AuthenticAMD.15:ao_scrub_policy = 1 set cpu_ms.AuthenticAMD.15:ao_scrub_rate_dcache = 0 set cpu_ms.AuthenticAMD.15:ao_scrub_rate_l2cache = 0 set mc-amd:mc_no_attach=1 set disable_memscrub = 1 Best regards, Oliver -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
