[zfs-discuss] System started crashing hard after zpool reconfigure and OI upgrade
I have two identical Supermicro boxes with 32GB ram. Hardware details at the end of the message. They were running OI 151.a.5 for months. The zpool configuration was one storage zpool with 3 vdevs of 8 disks in RAIDZ2. The OI installation is absolutely clean. Just next-next-next until done. All I do is configure the network after install. I don't install or enable any other services. Then I added more disks and rebuild the systems with OI 151.a.7 and this time configured the zpool with 6 vdevs of 5 disks in RAIDZ. The systems started crashing really bad. They just disappear from the network, black and unresponsive console, no error lights but no activity indication either. The only way out is to power cycle the system. There is no pattern in the crashes. It may crash in 2 days in may crash in 2 hours. I upgraded the memory on both systems to 128GB at no avail. This is the max memory they can take. In summary all I did is upgrade to OI 151.a.7 and reconfigured zpool. Any idea what could be the problem.

Does the Supermicro IPMI show anything when it crashes? Does anything show up in event logs in the BIOS, or in system logs under OI?

I'm sorry. I should have mentioned it that I can't find any errors in the logs. The last entry in /var/adm/messages is that I removed the keyboard after the last reboot and then it shows the new boot up messages when I boot up the system after the crash. The BIOS log is empty. I'm not sure how to check the IPMI but IPMI is not configured and I'm not using it. Just another observation - the crashes are more intense the more data the system serves (NFS). I'm looking into FRMW upgrades for the LSI now. On Wed, Mar 20, 2013 at 8:40 AM, Will Murnane will.murn...@gmail.comwrote: Does the Supermicro IPMI show anything when it crashes?

Great write up Jens. The chance of two MB to be broken is probably low but overheating is a very good point. It was on my to-do list to setup IPMI and seems that now is the best time to do it.

Re: [zfs-discuss] System started crashing hard after zpool reconfigure and OI upgrade
I can reproduce the problem. I can crash the system. Here are the steps I did (some steps may not be needed but I haven't tested it): - Clean install of OI 151.a.7 on Supermicro hardware described above (32GB RAM though, not the 128GB) - Create 1 zpool, 6 raidz vdevs with 5 drives each - NFS export a dataset zfs set sharenfs=rw=@10.20.1/24 vol01/htmlspace - Create zfs child dataset zfs create vol01/htmlspace/A $ zfs get -H sharenfs vol01/htmlspace/A vol01/htmlspace/A sharenfsrw=@10.20.1/24 inherited from vol01/htmlspace - Stop NFS shearing for the child dataset zfs set sharenfs=off vol01/htmlspace/A The crash is instant after the sharenfs=off command. I thought it was coincident so after reboot I tried it on another dataset. Instant crash again. I get my prompt back but that's it. The system is gone after that. The NFS exported file systems are not accessed by any system on the network. They are not in use. That's why I wanted to stop exporting them. And, even if they were in use this should now crash the system, right? I can't try the other box because it is heavy in production. At least not until later tonight. I thought I'll collect some advice to make each crash as useful as possible. Any pointers are appreciated. Thanks, -- Peter On Wed, Mar 20, 2013 at 8:34 AM, Peter Wood peterwood...@gmail.com wrote: I have two identical Supermicro boxes with 32GB ram. Hardware details at the end of the message. They were running OI 151.a.5 for months. The zpool configuration was one storage zpool with 3 vdevs of 8 disks in RAIDZ2. The OI installation is absolutely clean. Just next-next-next until done. All I do is configure the network after install. I don't install or enable any other services. Then I added more disks and rebuild the systems with OI 151.a.7 and this time configured the zpool with 6 vdevs of 5 disks in RAIDZ. The systems started crashing really bad. They just disappear from the network, black and unresponsive console, no error lights but no activity indication either. The only way out is to power cycle the system. There is no pattern in the crashes. It may crash in 2 days in may crash in 2 hours. I upgraded the memory on both systems to 128GB at no avail. This is the max memory they can take. In summary all I did is upgrade to OI 151.a.7 and reconfigured zpool. Any idea what could be the problem.
