Hi all, Not 100% sure if this is the correct list - or if there is a seperate hwraid list. I seem to be getting some random filesystem corruption on an IBM server that I use as a Xen Dom0. *** Specs *** Vendor: IBM Version: -[GGE149AUS-1.19]- Product Name: IBM System x3650 -[7979CBM]- AAC0: kernel 5.2-0[17003] Jul 25 2011 AAC0: monitor 5.2-0[17003] AAC0: bios 5.2-0[17003] AAC0: serial 5AB49E0 scsi0 : ServeRAID scsi 0:0:0:0: Direct-Access ServeRA Dom0_RAID6 V1.0 PQ: 0 ANSI: 2 scsi 0:1:0:0: Direct-Access IBM-ESXS MAY2073RC T107 PQ: 0 ANSI: 5 scsi 0:1:1:0: Direct-Access IBM-ESXS MAY2073RC T107 PQ: 0 ANSI: 5 scsi 0:1:2:0: Direct-Access IBM-ESXS MBC2073RC SC06 PQ: 0 ANSI: 5 scsi 0:1:3:0: Direct-Access IBM-ESXS ST973402SS B52B PQ: 0 ANSI: 5 scsi 0:1:4:0: Direct-Access IBM-ESXS ST973402SS B52B PQ: 0 ANSI: 5 scsi 0:1:5:0: Direct-Access IBM-ESXS ST973402SS B52B PQ: 0 ANSI: 5 scsi 0:1:6:0: Direct-Access IBM-ESXS ST973402SS B52B PQ: 0 ANSI: 5 scsi 0:1:7:0: Direct-Access IBM-ESXS ST973402SS B52B PQ: 0 ANSI: 5 scsi 0:3:0:0: Enclosure IBM-ESXS VSC7160 1.07 PQ: 0 ANSI: 3 I'm currently running kernel 3.11.4 and before the filesystem corruption seems to happen, I get a load of these: aac_write: aac_fib_send failed with status: -12 While this is going on, random things seem to fail. Eventually, I'll reboot the system and lots of tools will segfault - tracing it back leads to libraries that seem to have been corrupted. I can boot the system from rescue media, reinstall all the corrupted libraries / binaries and the system runs fine again for another few months before it happens again. arcconf shows: # arcconf getconfig 1 Controllers found: 1 ---------------------------------------------------------------------- Controller information ---------------------------------------------------------------------- Controller Status : Okay Channel description : SAS/SATA Controller Model : IBM ServeRAID 8k Controller Serial Number : 5AB49E0 Physical Slot : 0 Installed memory : 256 MB Copyback : Disabled Data scrubbing : Enabled Defunct disk drive count : 0 Logical drives/Offline/Critical : 1/0/0 -------------------------------------------------------- Controller Version Information -------------------------------------------------------- BIOS : 5.2-0 (17003) Firmware : 5.2-0 (17003) Driver : 1.2-0 (30200) Boot Flash : 5.1-0 (17002) -------------------------------------------------------- Controller Battery Information -------------------------------------------------------- Status : Okay Over temperature : No Capacity remaining : 100 percent Time remaining (at current draw) : 3 days, 20 hours, 56 minutes -------------------------------------------------------- Controller Vital Product Data -------------------------------------------------------- VPD Assigned# : 39R8875 EC Version# : J85096 Controller FRU# : 25R8076 Battery FRU# : 25R8088 ---------------------------------------------------------------------- Logical drive information ---------------------------------------------------------------------- Logical drive number 1 Logical drive name : Dom0_RAID6 RAID level : 6 Status of logical drive : Okay Size : 419400 MB Read-cache mode : Enabled Write-cache mode : Enabled (write-back) Write-cache setting : Enabled (write-back) Partitioned : Yes Number of segments : 8 Stripe-unit size : 256 KB Stripe order (Channel,Device) : 0,0 0,1 0,2 0,3 0,4 0,5 0,6 0,7 Defunct segments : No Defunct stripes : No Does anyone have any thoughts on this? -- Steven Haigh Email: netwiz@xxxxxxxxx Web: https://www.crc.id.au Phone: (03) 9001 6090 - 0412 935 897 Fax: (03) 8338 0299
