It was the same cause for us by the looks of it, on a Dell PowerEdge R720XD running Ubuntu 12.04.

comment Set iDRAC IP Address on Ubuntu 12.04 without Reboot?
Just so you know, I'm not ignoring your answer, I'm just trying to find a convenient time to try this on our systems. When I've had chance I'll mark this as the correct answer. Thanks for taking the time to answer!

comment Parallel mysqlimport Syntax Wrong?
Do you know any way of getting mysqlimport to tell me which file it is in? We have nearly 900 tables to import, many of which are too large to open in a text editor on Windows!

comment Parallel mysqlimport Syntax Wrong?
I have yeah.. it imports fine with MySQL Workbench (one table at a time). I've just looked inside the SQL and it looks like ALL the tables have the WRITE line: LOCK TABLES 'test_table' WRITE; /*!40000 ALTER TABLE 'test_table' DISABLE KEYS */;

Don't suppose you ever got chance to look this up?

comment Set iDRAC IP Address on Ubuntu 12.04 without Reboot?
Ok thanks for your answer. I can't risk doing this on these servers just in case it interferes with the bonding for whatever reason (I know it shouldn't). Next time we're at the data centre stood next to the machine I'll try this method (if I find no other way in the meantime). I'll mark this as the answer if no one comes up with anything with racadm. Thanks.

The dedicated iDRAC port seems to be completely disabled until you enable the enterprise license, so I think we need to used a shared NIC for now. We don't know any way of enabling enterprise without first gaining access to it via the web GUI. The server is in production with bonded network interfaces, so we can't change the server IP to 192.168.0.x while we do this, or we might as well reboot into the BIOS and do it :(

I did a check for badblocks sudo badblocks -nvs /dev/sdb1, but it came back with Pass completed, 0 bad blocks found. (0/0/0 errors). So looks like your suggestion has to be the next step.

comment Dell PowerEdge R720 - Corrupted RAID
Think we will have to do this, but before I do, I wanted to be 100% sure that none of the disks are bad/going bad. I don't want to just start the filesystem again to find that it does the same in a few weeks. I've tested all the drives with the Dell diagnostic tools which is saying no problems found, but when I check the "virtual disk" in iDRAC, it's saying "Bad Blocks Found: Yes" on the RAID?

comment Dell PowerEdge R720 - Corrupted RAID
@Iain It does seem to be using all the memory incredibly quickly. It exhausted our 64gb of memory in well under 5 minutes. I have a feeling adding swap may not help and there's something else going wrong here? Doubt we'd have disks big enough to add enough swap anyway with how it was burning through memory.
