Adaptec Raid 31605

One of our storage servers that has had problems in the past. Originally it seemed like XFS was having a problem with the large filesystem, so, we gambled and decided to use btrfs. After eight days running, the machine has gotten extremely slow for disk I/O to the point where backups that should take minutes, were taking hours.

Switching the disk scheduler from cfq to noop to deadline appeared to have only short-term benefits at which point the machine bogged down again.

We’re running an Adaptec 31205 with 11 Western Digital 2.0 terabyte drives in hardware Raid 5 with roughly 19 terabytes accessible on our filesystem. During the first few days of backups, we would easily hit 800mb/sec inbound, but, after a few machines had been backed up to the server, 100mb/sec was optimistic with 20-40mb/sec being more normal. We originally attributed this to rsync of thousands of smaller files rather than the large files moved on some of the earlier machines. Once we started overlapping machines to get their second generational backup, the problem was much more evident.

The Filesystem:

The machine

As it stands, we appear to be running out of Metadata space. Since our used metadata space is more than 75% of our total metadata space, updates are taking forever. The initial filesystem was not created with any special inode or leaf parameters, so, it is using the defaults.

The btrfs wiki points to this particular tuning option which seems like it might do the trick. Since you can run the balance while the filesystem is in use and check its status, we should be able to see whether it is making a difference.

I don’t believe it is going to make a difference as we have only a single device exposed to btrfs, but, here’s the command we’re told to use:

After a while, the box returned with:

So it added 1GB to the metadata size. At first glance, it is still taking considerable time to do the backup of a single machine of 9.7gb – over 2 hours and 8 minutes when the first backup took under 50 minutes. I would say that the balance didn’t do anything positive as we have a single device. I suspect that the leafsize and nodesize might be the difference here – requiring a format and backup of 8.6 terabytes of data again. It took two and a half minutes to unmount the partition after it had bogged down and after running the balance.

XFS took 52 minutes to back up the machine. XFS properly tuned took 51 minutes. Btrfs tested with the leafnode set took 51 minutes. I suspect I need to run things for a week to get the extent’s close to filled again and check it again. In any case, it is a lot faster than it was with the default settings.

Windows device driver information for Adaptec RAID 31205

The storage controller Adaptec RAID 31205 is part of a large Adaptec PCIe series that features high performance SAS (Serial Attached SCSI) and the cost effective Serial ATA to allow single storage solution. The Adaptec RAID 31205 also makes use of Unified Serial Architecture, an exclusive feature from Adaptec for controllers that supports both SATA and SAS disk drives. Other line of controller products within this series also supports 4, 8, 12 and 16 disk drives. The new Adaptec RAID 31205 controller also features a 12 port controller that is composed of 3 SAS connectors. Each of these connectors can be linked to a fan out cable. This set up allows connection of 4 SATA disk drives. The RAID 31205 card has 256 MB DDR2 RAM. RAID 31205 controllers operates within Adaptec's storage manager with its application having the full intuitive user interface capability that essentially allows user to view all RAID products. Upon installation of RAID 31205 in the client's server, the client can then sort all disk drives into logical drives.
