I can reliably reproduce the issue on a heavily modifed VA kernel based on 2.2.18. Is there a kernel which is believed to be a known good kernel? (both 2.2.x and 2.4.x) Failure pattern: System: mylex raid 5 array 8 x 9G drives (not really all that big) >=512M of RAM (1G of RAM works) no swap (Not sure if this makes a difference.) The system is attempting to create a single partition containing the most of the entire RAID array. errors: buffy: Installing with LIVE AMMO Creating partitions... Initializing filesystems... Out of Memory: Killed process 106 (portmap), saved process 2165 (mke2fs).<3>Out of Memory: Killed process 2123 (buffy), saved process 2165 (mke2fs).willow: LOAD FAILED <3>Out of Memory: Killed process 195 (sisyphus_upload), saved process 2165 (mke2 fs).<3>Out of Memory: Killed process 2165 (mke2fs). (Note that most of the above proccesses were dialog interfaces waiting for user input or perl scripts waiting for mke2fs or buffy to exit.) PS- Conversations with various VA empolyees indicates that others within VA, and at least one vendor are seeing hangs while creating really large filesystems on RAID arrays. (mostly 1/4 TB or larger) These issues appear to come and go, and are endemic to the 2.2.x kernel line. Both lnz and tytso seem to believe the issues to be vm entirely related. -- Solving people's computer problems always requires more hardware be given to you.
