>Description:
Doing tar -zxf about_5MB_file.tgz; rm -rf all_extracted cause kernel panic
on a tunefs -n enable file system (tmp in this case). Some times even
tar -xzf file cause this panic.
Here are the setting on /tmp:
tunefs -p /tmp
tunefs: soft updates: (-n) enabled
tunefs: maximum contiguous block count: (-a) 15
tunefs: rotational delay between contiguous blocks: (-d) 0 ms
tunefs: maximum blocks per file in a cylinder group: (-e) 2048
tunefs: minimum percentage of free space: (-m) 8%
tunefs: optimization preference: (-o) time
>How-To-Repeat:
tar -zxf about_5MB_file.tgz; rm -rf all_extracted (about 3-5 times)
>Fix:
I'm too far away from FS :)
