Hallo Cluster and GFS Experts,
I'm a new subscriber of this mailing list and appologise
in the case my posting is offtopic.
I'm looking for help concerning a corrupt gfs2 file system
which could not be recovered by me by fsck.gfs2 (Ver. 3.0.9)
due to to less less physical memory (4GB) eaven if increasing it
by a additional swap space (now about 35GB).
I would like to parse a image created of the lost fs (the first 6TB)
with the code provided in the new gfs2-utils release.
Due to this circumstance I hope to find in this mailing list some hints
concerning an automated step by step recovery of lost data.
Many Thanks in advance for your help
Markus
PS.: some infos concerning the damaged fs:
