Re: Linux 2.4.18 on RH 7.2 - odd failures

I have a little script that makes a bunch of large files to give the filesystem a beating. It goes like this:

for((i=0;i != 301;i++)); do

  echo $i

About 4 files in, it dies with 'dd: writing `./bigfile.4': Read-only file system'

This may be a dumb question, but you do have more than 4GB of space available on the RAID array when you start, correct? From this script, you'll need 300GB in order to not run out, because when the block size for dd is 1024k (1 meg), and the count is 1024, that's 1024 megabytes, or 1GB. Since you're writing out 300 of those 1GB files, I could see why the filesystem might run out of room.

Although the "journal block not found" message *does* point to general data corruption, you never know, this might have something to do with it too.
