that's actually a really crucial advantage for reiserfs. i use it on all
my squid boxes because reiserfs has the system back up and running in a
few seconds. e2fsck could take literally hours.

the fsck time for ext2 on a large partition with many thousands of files
meant that it was faster and cheaper (downtime means bad reputation and
lost customers and lost income) to just reformat the partition. e.g. a
power failure that took out my 3 LVS load-balanced proxy servers would
mean throwing away nearly 100GB of cached objects (3 servers x 4 cache
drives x 9GB per drive, running at about 90% full =~ 97GB).

reiserfs is pretty stable too. until the recent replacement of the huge
UPS in the server room, 2 of the proxies and the LVS dispatcher box had
an uptime of 374 days each (the third proxy had an uptime of only about
120 days due to a hard disk failure last year). they've been running
flawlessly for over a year. was sorry to have to reboot them.

this was with kernel 2.2.14 + reiserfs 3.5.17 + some other patches.

i'd recommend reiserfs for any linux based squid box.
