atacontrol missing drive after upgrade to 6.3
I upgraded from 6.2 to 6.3 p5 last night. Upon rebooting, the second disk in the mirror is missing. # atacontrol status ar0 ar0: ATA RAID1 status: DEGRADED subdisks: 0 ad0 ONLINE 1 MISSING # grep ata /var/run/dmesg.boot ad0: 238475MB WDC WD2500AVJB-63UDA0 00.02C01 at ata0-master UDMA100 ad1: 238475MB WDC WD2500AVJB-63UDA0 00.02C01 at ata0-slave UDMA100 ar0: disk0 READY (master) using ad0 at ata0-master ar1: disk1 READY (mirror) using ad1 at ata0-slave I am unsure how to re-add the disk, or if this is a bug. I noticed a number of fixes for atacontrol.c beyond the current version in 6.3 (1.36.2.6) http://www.freebsd.org/cgi/cvsweb.cgi/src/sbin/atacontrol/atacontrol.c Obviously it won't rebuild # atacontrol rebuild ar0 atacontrol: ioctl(IOCATARAIDREBUILD): Input/output error Do I do? atacontrol detach ata0-slave atacontrol attach ata0-slave atacontrol addspare ad1 ar0 atacontrol rebuild ar0 (not sure what channel I am supposed to be using) Or is this something that requires atacontrol.c to be patched? I am not sure where to start, so I thought I would ask here first before trying anything. btw, its Intel ICH5: atapci1: Intel ICH5 SATA150 controller port 0xc000-0xc007,0xc400-0xc403,0xc800-0xc807,0xcc00-0xcc03,0xd000-0xd00f irq 18 at device 31.2 on pci0 Thank you in advance for any help you can provide.

- Original Message From: Jeremy Chadwick [EMAIL PROTECTED] You're using Intel MatrixRAID, aren't you? Please migrate away from this immediately, your data is at risk. Ummm... I don't think so. It is just a standard RAID 1 mirror using the built in ICH5 chip. It has been running fine for a over a year now on the other builds of FreeBSD 6.x. It is not RAID 0+1 or whatever the Matrix RAID thing is. Make the switch to the world#39;s best email.

You're using Intel MatrixRAID, aren't you? Please migrate away from this immediately, your data is at risk. Although I am not using Matrix RAID, I guess I will switch to gmirror to be safe. Does the following approach seem valid? 1) Break the mirror (ar0) 2) Reboot using ad0 3) (from the link http://lantech.geekvenue.net/chucktips/jason/chuck/1175552464/index_html ): Step 1: Use sysctl to allow the mounted disk to be modified Step 2: Create the mirror (gm0) using ad0 with gmirror Step 3: Modify /boot/loader.conf to load gmirror on startup Step 4: Replace ar0 with gm0 in /etc/fstab Step 6: Use gmirror insert command to add ad1 to gm0 Step 7: Check the mirroring status with gmirror statusShould I just call the mirror ar0 instead of gm0 and save doing step4? Any problem with that? Thanks in advance. Mark Make the switch to the world#39;s best email.
