Well my CCD was working fine for about 2months until I rebooted, i'm not = exactly certain whats wrong now but im dreading the fact that it might = be dead. The array strip was on 3 'old' Seagate 9gig SCSI hdd's, here's as much = info as i can work out. FreeBSD 4.5-STABLE from April 2002 sometime, it's generally VERY stable. da0 is the boot disk, da1 da2 and da3 were the raid array and da5 is = another disk that had a backup of most things off of the ccd incase this = happened. da4 exists but the drive itself has stopped spinning, i havnt = had time to get it pulled out of the system yet. da0 and da5 are both = already mounted fine and working as normal. exit:0 89 $ sudo disklabel -r da0 # /dev/da0c: type: SCSI disk: da0s1 label:=20 flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 255 sectors/cylinder: 16065 cylinders: 1105 sectors/unit: 17767827 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0=20 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 16993683 774144 4.2BSD 2048 16384 89 # (Cyl. 48*- = 1105*) b: 262144 0 swap # (Cyl. 0 - = 16*) c: 17767827 0 unused 0 0 # (Cyl. 0 - = 1105*) e: 512000 262144 4.2BSD 2048 16384 94 # (Cyl. 16*- = 48*) exit:0 102 $ sudo disklabel da0 # /dev/da0c: type: SCSI disk: da0s1 label:=20 flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 255 sectors/cylinder: 16065 cylinders: 1105 sectors/unit: 17767827 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0=20 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 16993683 774144 4.2BSD 2048 16384 89 # (Cyl. 48*- = 1105*) b: 262144 0 swap # (Cyl. 0 - = 16*) c: 17767827 0 unused 0 0 # (Cyl. 0 - = 1105*) e: 512000 262144 4.2BSD 2048 16384 94 # (Cyl. 16*- = 48*) exit:0 91 $ sudo disklabel -r da1 =20 disklabel: /dev/da1c: Undefined error: 0 exit:0 96 $ sudo disklabel da1 disklabel: ioctl DIOCGDINFO: Invalid argument exit:0 92 $ sudo disklabel -r da2 disklabel: /dev/da2c: Undefined error: 0 exit:0 97 $ sudo disklabel da2 disklabel: ioctl DIOCGDINFO: Invalid argument exit:0 93 $ sudo disklabel -r da3 disklabel: /dev/da3c: Undefined error: 0 exit:0 98 $ sudo disklabel da3 disklabel: ioctl DIOCGDINFO: Invalid argument exit:0 94 $ sudo disklabel -r da5 disklabel: bad pack magic number (label is damaged, or pack is = unlabeled) exit:0 100 $ sudo disklabel da5 # /dev/da5: type: SCSI disk: IBM-PSG=20 label: ST39175LC !# flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 255 sectors/cylinder: 16065 cylinders: 1106 sectors/unit: 17774160 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0=20 8 partitions: # size offset fstype [fsize bsize bps/cpg] c: 17774160 0 unused 0 0 # (Cyl. 0 - = 1106*) exit:0 103 $ cat /etc/ccd.conf ccd0 32 0 /dev/da1e /dev/da2e /dev/da3e exit:0 104 $ sudo ccdconfig -C -v ccdconfig: ioctl (CCDIOCSET): /dev/ccd0c: Invalid argument exit:0 106 $ sudo ccdconfig -g no concatenated disks configured exit:0 110 $ dmesg | grep da da0 at sym1 bus 0 target 0 lun 0 da0: <IBM-PSG ST39175LC !# 0350> Fixed Direct Access SCSI-2 device=20 da0: 80.000MB/s transfers (40.000MHz, offset 15, 16bit), Tagged Queueing = Enabled da0: 8678MB (17774160 512 byte sectors: 255H 63S/T 1106C) da2 at sym1 bus 0 target 2 lun 0 da2: <IBM-PSG ST39175LC !# 0350> Fixed Direct Access SCSI-2 device=20 da2: 80.000MB/s transfers (40.000MHz, offset 15, 16bit), Tagged Queueing = Enabled da2: 8678MB (17774160 512 byte sectors: 255H 63S/T 1106C) da3 at sym1 bus 0 target 3 lun 0 da3: <IBM-PSG ST39175LC !# 0350> Fixed Direct Access SCSI-2 device=20 da3: 80.000MB/s transfers (40.000MHz, offset 15, 16bit), Tagged Queueing = Enabled da3: 8678MB (17774160 512 byte sectors: 255H 63S/T 1106C) da5 at sym1 bus 0 target 5 lun 0 da5: <IBM-PSG ST39175LC !# 0350> Fixed Direct Access SCSI-2 device=20 da5: 80.000MB/s transfers (40.000MHz, offset 15, 16bit), Tagged Queueing = Enabled da5: 8678MB (17774160 512 byte sectors: 255H 63S/T 1106C) da1 at sym1 bus 0 target 1 lun 0 da1: <IBM-PSG ST39175LC !# 0350> Fixed Direct Access SCSI-2 device=20 da1: 80.000MB/s transfers (40.000MHz, offset 15, 16bit), Tagged Queueing = Enabled da1: 8678MB (17774160 512 byte sectors: 255H 63S/T 1106C) Mounting root from ufs:/dev/da0s1a da4 at sym1 bus 0 target 4 lun 0 da4: <IBM-PSG ST39175LC !# 0350> Fixed Direct Access SCSI-2 device=20 da4: 80.000MB/s transfers (40.000MHz, offset 15, 16bit), Tagged Queueing = Enabled da4: Attempt to query device size failed: MEDIUM ERROR, Medium format = corrupted exit:0 111 $ dmesg | grep sym sym0: <810a> port 0x2000-0x20ff mem 0xfa001000-0xfa0010ff irq 2 at = device 8.0 on pci0 sym0: No NVRAM, ID 7, Fast-10, SE, parity checking sym1: <896> port 0x3000-0x30ff mem = 0xfe000000-0xfe001fff,0xfe004000-0xfe0043ff irq 10 at device 3.0 on pci1 sym1: No NVRAM, ID 7, Fast-40, LVD, parity checking sym2: <896> port 0x3400-0x34ff mem = 0xfe002000-0xfe003fff,0xfe004400-0xfe0047ff irq 11 at device 3.1 on pci1 sym2: No NVRAM, ID 7, Fast-40, LVD, parity checking pass6 at sym1 bus 0 target 6 lun 0 Any and all suggestions welcomed. I would like to revive the CCD if at = all possible but if it isn't possible then I just need to know this so I = can work on rebuilding the lost data. Cameron Brunner inetsalestech.com
