Hello,
I recently added two disks to the mirror on my 3ware 9550 controller
with the intend to expand my mirror. It doesn't support that with
differently sized disks though, so I ended up creating a new mirror
and gconcat-ed them together. Now I'm seeing lots of UNKNOWN FILETYPE
and PARTIAL somethings if fsck verifies the disk, all in subsequent
inodes so it looks like fsck gets some offset wrong somewhere. It
started with a number of SOFTUPDATE INCONSISTENCY's, which of course
went away after disabling softupdates on that FS (it's hardly ever
written to anyway).
I originally created the concatted disk in two steps. First I created
the concat on my new mirrored disks and copied the files from my
existing mirror in there. Second I appended the existing mirror to my
concatted disk. It seemed to work fine, but now I'm seeing so much
errors that I can only mount the concat r/o!
Is there anything I can do to fix the issue? World is a stable from
just after the 7.2 release, I'm building a fresh one now.
Here are a few details:
