Every, thanks for the help. It does look like we have a disk problem. when I first checked we had only 44% of disk used, then about 1/2 later we were at 100%. And the application does NOT write anything to disk.
Soo, finally ran fsck again and it allowed me to do some fixing which got the disk down. The application is still running, a java application under tomcat, but since it does not write anything to the disk, it seems happy. We are going to configure another server and just move it over to there and then fix or trash the disk. Thank you for all the help. It enabled me to identify the problem. Dino, - since the application was still running, I was afraid to do something like a remount. Also the IT guy is in New York, so no one on site if I needed a manual restart. thanks very much everyone Ann Richmond Dino K wrote: > Did you try a manual rw remount? > > mount -o remount,rw > > -DK > > On Wed, Oct 26, 2011 at 4:00 PM, Ann <a...@randrinc.com > <mailto:a...@randrinc.com>> wrote: > > Jeff, > thanks for the ideas.
