What is believed to be the current status of the typical mke2fs
crashes/hangs due to vm issues? 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.
