Date: Tue, 2 Mar 2004 10:35:44 +0100 Message-ID: <200403021035.45201.bon@teamlog.Fr> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Return-path: list-help: list-unsubscribe: list-post: Errors-To: flx@namesys.com Content-Disposition: inline List-Id: Content-Type: text/plain; charset="us-ascii" To: reiserfs-list@namesys.com Hi all, I have a 40Go ide disk that is mounted with one big partition containing all my clients datas on a linux debian woody. I was working as usual on the server when I suddenly couldn't no more list the contents of the root mount point (/part) but could continue working and looking into the files all under the root, (/part/distrib) and can cd into all the sub-directories. I just can't access to the root partition contents with an error message that I unfortunately haven't keep. I decide to reboot the server in order to plug another ide disk to copy all data to this disk but, as soon as I umount the disk, I was unable to remount it. It replies me : mount: is not a repertory (traduction of the french error message). The reiserfsck do reply : root@interne:~# reiserfsck /dev/hdc1 <--------reiserfsck 3.6.4, 2002--------> Will read-only check consistency of the filesystem on /dev/hdc1 Will put log info to 'stdout' Do you want to run this program?[N/Yes] (note need to type Yes if you do):Yes ****************************************************** * Warning: The dma on your hard drive is turned off. * * This may really slow down the fsck process. * ****************************************************** ########### reiserfsck --check started at Tue Mar 1 15:19:46 2004 ########### Replaying journal.. 0 transactions replayed Checking internal tree../ 1 (of 2)bad_internal: vpf-10320: block 8384, items 5 and 6: The wrong order of items: [2 2310 0x52a2001 IND (1)], [0 2311 0x69db001 IND (1)] the problem in the internal node occured (8384), whole subtree is skipped finished Comparing bitmaps..vpf-10640: The on-disk and the correct bitmaps differs.

The first stage seem to pass correctly but the second pass loop infinitely on message : do_pass_2: The block (level=28869, nr_item=905, free_space=49895 rdkey), marked as a leaf on the first two passe, is not a leaf! Will be skipped. So do you have any suggestion on what I can do now and how I can acces again to my datas, even temporarily to copy them eslewhere? Thanks for your help. Jean-Michel.
