Hi guys, we notice on our Swift storage nodes some problems with our disks. After some time they blocks all I/O requests to the disks. Therefore the server isn't working suddenly and needs a reboot.
Serversetup: * Kernel 3.19.x * Ubuntu 14.04 * Swift (Kilo) * 12 x 2TB SATA (JBOD) * 2 x 480GB SSD (Raid1) * 32GB RAM * 8 Cores CPU The first try was an upgrade of the raid controller firmware and drivers. The second one some tests of writes and reads to each disk. I can't reproduce this issue but i heard on the last summit, Swift can be the problem by this issue. Do anyone solve this problem ? - Heiko -- anynines.com
