From the changelog of linux's ext2 fs source: - New file attributes: - Immutable files cannot be modified. Data cannot be written to these files. They cannot be removed, renamed and new links cannot be created. Even root cannot modify the files. He has to remove the immutable attribute first. - Append-only files: can only be written in append-mode when writing. They cannot be removed, renamed and new links cannot be created. Note: files may only be added to an append-only directory. - No-dump files: the attribute is not used by the kernel. My port of dump uses it to avoid backing up files which are not important. -- Anthony Wong.
Re: undeletable file (RESOLVED)
Thanks to all who responded to my question. I was able to delete the file last night by resetting attribute flags using chattr. The attribute flags on that file were ALL set! (Actually, this seems somewhat consistent with the group ID getting mysteriously changed to 65535). No other files were affected. --ken __ Ken Lauffenburger / /__ __ [EMAIL PROTECTED] / / D e b i a n G N U \ \/ / / / __ __ __ \ / / / / / / _ \ / / / / / \ ...Look out Bill, / /___ / / / / ) // (_/ / / /\ \ here comes...

I haven't tried going to single-user mode yet; I'm on a remote connection to this box. I had a similar predicament when fdisk changed some files to bizarre character devices. Even '?' showed up in the permissions as well as the huge group number. I posted a question on comp.os.linux.setup and got an answer that worked. What has happened is that the inode for that file (and probably others) has become hopelessly corrupted. Thankfully, you can delete this. Boot into single user mode so the fs with this file on it is unmounted (boot to a root disk if it's on the root partition to make it easier). # debugfs -w /dev/hda# # check man page to be sure; my notes # aren't here. debugfs prompt clri /path/fstodbdf #clear inode entry for this file debugfs prompt rm /path/fstodbdf #remove this offending file # e2fdsk /dev/hda# # make sure everything's hunky dorry. :) Ta da!

You can also try lsattr and see if the file has been made immutable. chattr -i will take off this flag. Allen Allen Smith, [EMAIL PROTECTED] IP Multicast.
