Hi,
on saturday a had a nice day with 16 houre to find a workaround to bring linux stable. I had moved the server from reiserfs to ext2 for all datafile areas. The move with tar runs without any crash. I had an about 60 to 75 MB/second transfer ( read + write) on the move of the oracle datafiles.
After startup of oracle and backup the open datafiles ( i know this is nonsens but its a good stress test) i get a crash. On a reiserfs this would crash immediately. On ext2 crash happend after about 2.5houres of backup ( about 80GB datafiles). After this i switched backup to kernel version 2.2.19. ---> The system runs now without crash. On other server without oracle but which are have tsm backup we had no problems with 2.4.16 ( at the moment only about 15 Servers)
Its seems that you are right an we have a serious vm bug. This bug is only viewable if you user oracle and tsm (tivoli storage manager) .... Strange.
Kinds regards
Oliver Schersand
