    I removed a volume from a domain and now the domain has panicked:

    The domain was:

    root@thor==> showfdmn -k home_domain

                  Id Date Created LogPgs Version Domain Name
    3d0e2d5a.0007c3dd Mon Jun 17 14:41:30 2002 512 4 home_domain

    I issued:

    rmvol /dev/disk/dsk15b

    and removed the volume.

    Now I can't do anything with /home. This message is in /var/adm/messages:

    Jul 15 15:07:57 thor vmunix:
    Jul 15 15:07:57 thor vmunix: bs_inherit - bmtr_get_rec failed, return code = -1043

    Jul 15 15:07:57 thor vmunix: An AdvFS domain panic has occurred due to either a metadata write error or an internal inconsistency. This domain is being rende

    Jul 15 15:07:57 thor vmunix: Please refer to guidelines in AdvFS Guide to File System Administration regarding what steps to take to recover this domain.

    in etc/fdmns/home_domain:

    lrwxr-xr-x 1 root system 16 Nov 12 2002 dsk12a -> /dev/disk/dsk12a
    lrwxr-xr-x 1 root system 16 Nov 12 2002 dsk12b -> /dev/disk/dsk12b

    lrwxr-xr-x 1 root system 16 Jul 14 15:31 dsk13f -> /dev/disk/dsk13f

    I tried advscan:

    root@thor==> /sbin/advfs/advscan -a -f home_domain

    Scanning devices /dev/rdisk/dsk0 /dev/rdisk/dsk4 /dev/rdisk/dsk12 /dev/rdisk/dsk13 /dev/rdisk/dsk5
                   /dev/rdisk/dsk6 /dev/rdisk/dsk7 /dev/rdisk/dsk1 /dev/rdisk/dsk8

    Attempting to fix link/dev_count for domain

           home_domain

    Nothing to fix

    but it still doesn't work.

    How can I fix this? Salvage seems overkill. Can I remove the links in /etc/fdmns/home_domain and recreate the home_domain from scratch using the same configuration?

    Thank you!!
