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 <MAXTOR STM3802110A 3.AAK> at ata0-master UDMA100 ad3: 76319MB <Seagate ST3802110A 3.AAJ> at ata1-slave UDMA100 At 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 buildword 3) 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.
On the documentation sacttered around on the net I read that
it's better to have 3 harddisks where one is for the main os
and the other two are mirrored in stead of a situation where
the OS resides on one of the two mirrored disks.
Can you give me some advice on this?
I have three identical seagate harddisks and want to put two
in a mirror setup with the OS on it, and use the other as
spare drive, in case sonmething goes wrong.
Thanks in advanced
