[raid] recover from disk error
2T x 2 is raid1 mirrored
- One day, I've found the one of the mirror pair got disk error
- Add spare (the box has four slots, and two disk were in the slot)
(disk label as the same as others)
raidctl -a /dev/wd2a raid0
-
raidctl -F /dev/wd0a raid0
This starts process to add spare disk
- It took 30 days to complete spare setup
- I was hesitating what to do for several days
- One day the box does not give any response
- Reboot
- Asking root device: wd0a
(and stopped)
- (force to shutdown)
- Remove suspicious unit
- Boot ... fine
u# /sbin/raidctl -s raid0

/dev/wd1a: optimal

[PC] dd does not duplicate Windows 11 boot disk ?
- PC = Windows 11
- boot external sd0 with NetBSD install image
- insert another bootable candidate SATA disk (with USB) 500GB
- dd if=/dev/wd0d of=/dev/sd0 bs=64m
- unrecorded error at the end

[NetBSD] installboot (Although it’s too late)
今更ながら install boot
(the same entry 6 Mo ago)
NetBSD/x86 ffsv2 Primary Bootstrap
Boot failed (errno 2): Can't open /boot
Recently I'm getting above issue.
- using sysinst Advent calendar 2016
- NetBSD/amd64 11.99.1 (but not limited to)
- RAID1 configuration (by sysinst)
- manual installboot is necessary
After usual sysinst, I would do
- mount /dev/raid0a /mnt
- chroot /mnt
- mount -a
- cd /usr/mdec
installboot -fv -t raid /dev/wd0a bootxx_ffsv1 /boot
installboot -fv -t raid /dev/wd1a bootxx_ffsv1 /boot
raidctl -A softroot raid0
The issue is:
- Is raid0 by above setup is ffsv1 or ffsv2 (See bellow, saying ffsv1)
- Is destination partition correct ?
