I can't be able to access/write to ad10 using fdisk for example... under FreeBSD-5.x (OS version installed on the server). But I gave a try to the CD "4.9-i386-mini.iso" and... I succeed to create a slice on ad10 and even to partition and write some files on it! So, what I can say here: - The disk seems not to be dead; - But after I had modify it under the 4.9 CDROM, I can't access it (fdisk, bsdlabel, etc.) under the installed and running OS on this machine: FreeBSD 5.2.1. :( It seems that 'Joan' was in the right direction arguing to play with "kern.geom.debugflags", but it didn't work for me. If someone has an other idea with this new point in mind...

Well, I see that geom tastes ad10 and creates a slice class for it... However, if kern.geom.debugflags=16, you should still be able to touch the slice. If debugflags=16 I know of no reason why you shouldn't be able to partition de disk; sorry, I'm stumped :( qvb -- pica ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

What we ca note is that: - The machine was booted without using this drive at all (nor in a 'ar' array, nor alone via 'ad10'); - GEOM create an entry for this device during the boot proccess (see below), but there is no reference to use it from the OS point of view (/etc/fstab, etc.). - How can I _really_ know that this drive is not used by geom? # dmesg | tail -50 [...] GEOM: create disk ad4 dp=0xc6cb6360 ad4: 78167MB [158816/16/63] at ata2-master UDMA133 GEOM: create disk ad6 dp=0xc6ab2960 ad6: 78167MB [158816/16/63] at ata3-master UDMA133 GEOM: create disk ad8 dp=0xc6ab2560 ad8: 117246MB [238216/16/63] at ata4-master UDMA133 GEOM: create disk ad10 dp=0xc6ab2660 ad10: 117246MB [238216/16/63] at ata5-master UDMA133 GEOM: create disk ar0 dp=0xc6aae5e0 ar0: 78167MB [9964/255/63] status: READY subdisks: disk0 READY on ad4 at ata2-master disk1 READY on ad6 at ata3-master Mounting root from ufs:/dev/ar0s1a g_slice_config(ad10, 0, 0) g_slice_config(ad10, 1, 0) g_slice_config(ad10, 2, 0) g_slice_config(ad10, 3, 0) g_slice_config(ad10, 0, 1) g_slice_config(ad10, 1, 1) g_slice_config(ad10, 2, 1) g_slice_config(ad10, 3, 1) This is what we can expected to see: the only 'ar' array which exist now is the first mirror for system part.

You should take ad8 out of the array first. I don't think so, /dev/ad8 has no problem and is actually in active use. Let me be more precise here: The "system" (/, /tmp, /usr and /var) is mounted on a mirror represented by /dev/ar0 made with /dev/ad4 and /dev/ad6. The "data" (/home) was previously mounted on the device /dev/ar1 which was made with /dev/ad8 and /dev/ad10. Because /dev/ad10 seems to have a problem I made a backup, broke the mirror seen as /dev/ar1 and simply put /home on /dev/ad8 - freshly restored. >> Because the problematic disk is not actually used, I can try some >> commands on it if someone think it may be interesting. > On the hardware side, you should look for some diagnostic tool from the > manufacturer.

I take it that you are still trying to manage ad10 through the RAID capable controller. No real information but I would guess the controller is still seeing information on the drive ad10 which ties it in with some other disk for RAID. If you have a regular on board ATA interface I'd try plugging the drive in there (you can do it with all other drives removed for safety) and then try to initialise using an installation CD. If that works I imagine you can put every thing back in your prefered configuration and continue.

Before that, a /home was mounted on the device corresponding to the mirror, i.e. /dev/ar1 (which was made from /dev/ad8 + /dev/ad10).
