Re: [gentoo-user] BIG reiserfs problem

I wrote five because I started to count 5 times ago. My RAM is in good
condition :) Problem with reiserfs (reiser4 is used across the net to
specify version 4.X IMHO) occurs on many machines - servers, backup servers
(rsync once a day), desktop computers (3 or 4), laptop (only one).
  Every one of them was tested and works with ext3 (but it has limit of
subdirs), every one of them works fine under UFS2 (freebsd, limit of dirs,
too). Some of those servers work hard with mysql,php,apache (more than 2000
queries per second) and errors occurs randomly... 1 per week.
 Backup servers doesn't do very much - only one rsync process at a time and
this is enough to break reiserfs.

To resume:
1. reiserfs breaks down on power failures even with option data=journal or
sync
2. reiserfs breaks down on every machine that I have - from pentium-mmx to
Core2Duo, about 10 machines
3. reiserfs breaks down on heavy load (/proc/loadavg=35), and low load(=0.1),
*it only takes a time*
4. reiserfs broke down on all partitions that was using reiserfs
5. reiserfs breaks down on 2.4.21+ and some older
6. reiserfs breaks down on 2.6.17,  ..18 and older that I can't remember
7. ram, disks, cables was tested, changed, and problem stays
8. ...sata, ata/pata
9. maybe those are just accidents but they occur too often to call them just
accidents

Conclusions:
1. UPS will not help you with reiserfs
2. Do not use reiserfs on production systems
3. "quite stable" means "works for them, not for me".
4. journal only slows things down and does not preserve any consistency

My questions:
1. Is there the file system that preserves data & metadata like UFS2 ????
"solid as rock!"
2. What options do I need to enable (mount/mkfs) for XFS or JFS to enable
FULL journaling?
3. How to bypass limit od 32000 dirs on ext3?
4. Is there an option in kernel and how to enable it to sync on Oops and
reboot?
