Hi, (Please Cc: me in your replies, I am not subscribed.) I am using: % obiwan:tataz$ uname -mv % FreeBSD 6.1-STABLE #8: Sun Jun 25 18:27:14 CEST 2006 root@obiwan:/usr/obj/usr/src/sys/OBIWAN i386 I have set up a mirror gm1 using gmirror(8), with ad1 and ad2 as providers. This had worked pretty well for weeks, until I got the following error: % ad1: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=40<UNCORRECTABLE> LBA=6170832 % GEOM_MIRROR: Request failed (error=5). ad1[READ(offset=3159465984, length=65536)] % GEOM_MIRROR: Device gm1: provider ad1 disconnected. Obviously, my hard drive (Maxtor's drives really, really suck) is going sick. But as usual, a mere reboot seems to improves the disk state, for a while at least. I have rebooted the box, but now the kernel says: % GEOM_MIRROR: Device gm1 created (id=1340871616). % GEOM_MIRROR: Device gm1: provider ad1 detected. % GEOM_MIRROR: Device gm1: provider ad2 detected. % GEOM_MIRROR: Component ad1 (device gm1) broken, skipping. And gmirror(8)'s output is: % Geom name: gm1 % State: DEGRADED % Components: 2 % Balance: split % Slice: 4096 % Flags: NONE % GenID: 1 % SyncID: 1 % ID: 1340871616 % Providers: % 1. Name: mirror/gm1 % Mediasize: 81964301824 (76G) % Sectorsize: 512 % Mode: r1w1e2 % Consumers: % 1. Name: ad2 % Mediasize: 81964302336 (76G) % Sectorsize: 512 % Mode: r1w1e1 % State: ACTIVE % Priority: 0 % Flags: NONE % GenID: 1 % SyncID: 1 % ID: 1733588705 What am I suppose to do from here ? I've performed the following commands: % obiwan:root# gmirror forget gm1 ad1 % obiwan:root# gmirror insert gm1 ad1 But the whole disk is then wholly resynchronized. Is there any faster way to reconnecte ad1 to gm1 ? Thank you ! -- Jeremie Le Hen < jeremie at le-hen dot org >< ttz at chchile dot org >
