Hi Gurus,
I have two D1000 attached to Sun Netra T105 both are configured with
Disksuite metadevice. Last week in one of the D1000 three disks failed
and since then box didn't came up. When i boot the box it gives
following error:
NOTICE: md: mddb: parsing error on 'sd:143:-1'
NOTICE: md: mddb: parsing error on 'sd:159:-1'
metainit: sciaswls04: stale databases
Insufficient metadevice database replicas located.
Use metadb to delete databases which are broken.
Ignore any "Read-only file system" error messages.
Reboot the system when finished to reload the metadevice database.
After reboot, repair any broken database replicas which were deleted.

I can't modify any files. All filessytems are read-only. If i try to
edit vfstab or system files to disable both metadevices. It gives an
error as /var/tmp not found. The box is at co-location so i can't put
boot from CD as well. I can't bring the box up. Below is the df output.
How do i resolve this issue. Please advice.
Regards
shahb
