Thanks in advanced Dino Vliet Dino, We're running all of our firewalls now with gmirror. Our setup uses a hot-swap SCSI setup, whereas you're using ATA disks. Keep in mind that, to remove the drives, you'll more than likely need to shut down the system. Have the third drive in there as a back up will certainly buy you time. Follow the how-to I've written at https://www.secure-computing.net/wiki/index.php/Gmirror , and simply don't do any configuration on the third drive in the system. When one fails, you'll then remove, or 'forget' the failed drive, and add in the hot-spare you've got in the system.

geom gmirror question
Forwarded Message From: "Dino Vliet" <[EMAIL PROTECTED]>CC: [EMAIL PROTECTED] To: freebsd-questions@freebsd.orgDate: Sat, 7 Apr 2007 03:55:20 -0700 (PDT)Subject: hardware problems?..how to disable geom?Plain Text Attachment [ Scan and Save to Computer ] Hi folks,I have sinned:-(I have (for testing purposes) activated geom for mirroring on my freebsd 6.2 via c3 cpu system. However, I used two different brand IDE harddisks but identical in capacity.I have: ad0: 76319MB at ata0-master UDMA100 ad3: 76319MB at ata1-slave UDMA100At first everything worked, but lately I have noticed some weird things: 1) In the beginning the gmirror status command was showing the complete status for the components ad0 or ad3 (it was altering I guess due to the round robin thing I choose) However since a few weeks, only the ad0 component shows the complete status(the only thing I did in between was removing the seagate harddisk once to try to go to a pc mall and buy a second one but when I returned I just reattached it (I hadn't switched the pc on though in the mean time so I don't think it's an issue))2) I started to have problems building the ports and make buildword3) bash core dumped on my (I couldn't log in nomaly anymore and had to use csh)4) now I see that rsyncd, freshclam and clamav are core dumping when the machine boots up: GEOM_MIRROR: Device gm0: provider ad3 detected. GEOM_MIRROR: Device gm0: provider ad3 activated. GEOM_MIRROR: Device gm0: provider ad0 activated. GEOM_MIRROR: Device gm0: provider mirror/gm0 launched. Trying to mount root from ufs:/dev/mirror/gm0s1a pid 896 (rsync), uid 0: exited on signal 4 (core dumped) pid 928 (clamd), uid 0: exited on signal 4 (core dumped) pid 934 (freshclam), uid 0: exited on signal 4 (core dumped) So I want to bring the machine back to its normal state by doing this:a) remove seagate harddisk b) remove the mirror c) see if everything works fine again because I don't want to reinstall (I CAN GET AWAY WITH THIS RIGHT?)The question is, how di I get rid of the mirror? Or is it better to order a new seagate harddisk, get rid of the maxtor harddisk and install the new seagate harddisk in stead of the maxtor one and rebuild the mirror?Thanks for your kind help *** Hi folks, I've bought my new hardware and want to give this another try.
