kernel error

phan — Tue, 09 Jan 2001 13:44:58 GMT

Recently, the following error message appeared in my message logs (see file attached).

The problem appeared after I deleted some files(over 90G) off the disk (raid structure).

A friend of mine gave me a first answer about the possible cause of the my problem, that is:
- the inode "table" may have error(s), so that I have a file (a directory or a normal file) which is not linked to by any inode.

Whatever the causes may be, can I recover from this "crash" ?

Note: I don't have the tool "fsdb" on my linux machine to debug the disks.

Please excuse me for my bad written english.

Please help. Thanks in advance.

There have been a variety of problems reported related to software raid on Linux and I suspect this is just another. To put it plainly, software raid should probably not be used in a production environment at this point. Performing and fsck may help for now, but you may need to rebuild the array. The size of your files suggests that a raid solution is needed, but I would suggest that a hardware based raid solution would be the way to go (DPT controller for example). There are a variety of other productivity gains that will be seen as well.

The problem might be older. The short term soluiton is fsck. I can be due a file system bug (your file system is quite big if you deleted 90GB), bad block or RAID as Tim mentioned.
