lupus in fabula as a follow up of my short intervention on raid1 with my machine to the thread "Debian on big systems".
System: supermicro H8QC8 m.board, two WD Raptor SATA 150GB, Debian amd64 lenny, raid1 While running an electronic molecular calculation - estimated to four days time - I noticed by chance on the screen (what is not in the out file of the calculation) that there was a disk problem. I took some scattered notes from the scree: RAID1 conf printout wd: 1 rd:2 disk0 wd:1 o:0 dev: sda6 disk0 wd:1 o:0 dev: sdb6 md: recovery of raid array md4 minimum guaranteed speed 1000 kB/sec/disk using max available idle I/O bandwidth but no more than 200000 .......................... Disk failure on sda1, disabling device Operation continues on 1 devices. raid sdb1: redirecting sector 262176 to another mirror RAID1 conf printout wd:1 rd:2 .......................... disk1, wd:0 0:1 dev:sdb7 ================= Then, the electronic molecular calculation resumed - with all CPUs at work, as indicated by top - and in its output file there was no trace of the above problems. Command: lshw -class disk reported: *-cdrom description: DVD writer product: PIONEER DVD-RW DVR-111D vendor: Pioneer physical id: 0 bus info: i...@0.0 logical name: /dev/hda version: 1.02 capabilities: packet atapi cdrom removable nonmagnetic dma lba iordy pm audio cd-r cd-rw dvd dvd-r configuration: mode=udma4 status=nodisc *-disk:0 description: SCSI Disk physical id: 0 bus info: s...@0:0.0.0 logical name: /dev/sda size: 139GiB (150GB) *-disk:1 description: ATA Disk product: WDC WD1500ADFD-0 vendor: Western Digital physical id: 1 bus info: s...@1:0.0.0 logical name: /dev/sdb version: 20.0 serial: WD-WMAP41173675 size: 139GiB (150GB) capabilities: partitioned partitioned:dos configuration: ansiversion=5 signature=000b05ba The description of disk 0 was cryptic to me. ==================== As there have been RAM problems, I also run lshw -class memory all DIMMs are correctly reported. No mem problem. =============== Then I run: /proc/mdstat the output was: Personalities : [raid1] md6 : active raid1 sda8[2](F) sdb8[1] 102341952 blocks [2/1] [_U] md5 : active raid1 sda7[2](F) sdb7[1] 1951744 blocks [2/1] [_U] md4 : active raid1 sda6[2](F) sdb6[1] 2931712 blocks [2/1] [_U] md3 : active raid1 sda5[2](F) sdb5[1] 14651136 blocks [2/1] [_U] md1 : active raid1 sda2[2](F) sdb2[1] 6835584 blocks [2/1] [_U] md0 : active raid1 sda1[2](F) sdb1[1] 2931712 blocks [2/1] [_U] md2 : active raid1 sda3[2](F) sdb3[1] 14651200 blocks [2/1] [_U] unused devices: <none> =============== I would appreciate advice. thanks francesco pietra -- To UNSUBSCRIBE, email to debian-amd64-requ...@lists.debian.org with a subject of "unsubscribe".
