We have a script that adds corruption to ext2/3/4 filesystems and runs e2fsck on it. It definitely could be improved, but it still catches some occasional errors: http://git.whamcloud.com/?p=tools/e2fsprogs.git;a=commit;h=aee44c669bebe29bfdb8a1c86da443234f8bc257 It tries to format the filesystem with different features and options, then adds corruption from both random data and copying parts of

Hello, I am running 2 servers with CentoS 5.4 32 bit with 1 GB memory and 2 Xeon 3,4 Ghz cpu's. Both are server and client. Gluster 3.0.4 source is used and the latest fuse from glusterfs. I put the Qmail maildir on the gluster mount. I notices that IMAP connections are really slow and see a lot of gluster load whenever I receive a mail or send an email.

Hi - I'm searching for file system corruption tool, say it inject disk-errors like multiply owned blocks etc. Later an integrity scan process (like e2fsck) will verify on-disk layout and fix these errors. I'd like to read/understand such tools before writing one for an proprietary on-disk file system. Do we have such tools for ext{2,3,4}fs ? Thanks for any help or pointers! -- ----

Hi - Updated my old project named "ext3carve" and renamed it as "extcarve" . It uses libext2fs. (To be precise,re-uses on 'debugfs' command's "dump_unused" feature) In summary,the tool will do the following - It will scan the linux machine ,for unused/deleted blocks and search for magic signatures. If it finds valid signature (both header and footer) It

Hi All, I'm having a problem with cross subnet browsing and name resolution across an openvpn tunnel. i've found quite a few people who've had the same on mail lists but none of their fixes have worked.

What about your openvpn config? The tun net must have an entry in your hosts allow. If you work with briding the remote network has to be the same subnet as the local!? Bridging is the best way to have a remote net integrated. I have one logging in form Berlin on my Samba-Domain.
