I guess you are pretty tired of me by now, but I hope there is some patience left out there. I have the following scenario: Netra X1, two Seagate Barracuda-drives that both claim to be 80GB in size. In reality, they differ by 300 megs or so in available size. /dev/ad0 is the smaller one. /dev/ad1 is the bigger one. I install FreeBSD on the smaller drive, do all the gmirror stuff, copy all contents on /dev/ad0 to /dev/mirror/gm0 (/dev/ad1 inserted in the raid), edit fstab and loader.conf on both /dev/ad0 and /dev/ mirror/gm0 to point the root directory to /dev/mirror/gm0. Then I reboot. And suddenly, /dev/ad1 is listed as /dev/ad0 when I do a gmirror status. klingklang# gmirrror status gmirrror: Command not found. klingklang# su - klingklang# klingklang# gmirror list Geom name: gm0 State: COMPLETE Components: 1 Balance: round-robin Slice: 4096 Flags: NONE GenID: 0 SyncID: 1 ID: 1464945542 Providers: 1. Name: mirror/gm0 Mediasize: 80026361344 (75G) Sectorsize: 512 Mode: r1w1e1 Consumers: 1. Name: ad0 Mediasize: 80026361856 (75G) Sectorsize: 512 Mode: r1w1e1 State: ACTIVE Priority: 0 Flags: DIRTY GenID: 0 SyncID: 1 ID: 2076583338 The original /dev/ad0 is now known as /dev/ad1 and of course, now it's too small to be added to the raid. Also, note that the size of / dev/mirror/gm0 and /dev/ad0 in the above list differs. The easy solution would to simply switch places of the drives, re- install FreeBSD and then the problem would be solved, but it turns out it isn't. I've tried that too, and result is still the same for some reason that I don't understand. I'm tearing out whatever hair I have left as I've spent an entire weekend working on solving this. Thanks for you patience. Joacim
