I wrote five because I started to count 5 times ago. My RAM is in good |
2 |
condition :) Problem with reiserfs (reiser4 is used across the net to |
3 |
specify version 4.X IMHO) occurs on many machines - servers, backup servers |
4 |
(rsync once a day), desktop computers (3 or 4), laptop (only one). |
5 |
Every one of them was tested and works with ext3 (but it has limit of |
6 |
subdirs), every one of them works fine under UFS2 (freebsd, limit of dirs, |
7 |
too). Some of those servers work hard with mysql,php,apache (more than 2000 |
8 |
queries per second) and errors occurs randomly... 1 per week. |
9 |
Backup servers doesn't do very much - only one rsync process at a time and |
10 |
this is enough to break reiserfs. |
11 |
|
12 |
To resume: |
13 |
1. reiserfs breaks down on power failures even with option data=journal or |
14 |
sync |
15 |
2. reiserfs breaks down on every machine that I have - from pentium-mmx to |
16 |
Core2Duo, about 10 machines |
17 |
3. reiserfs breaks down on heavy load (/proc/loadavg=35), and low load(=0.1), |
18 |
*it only takes a time* |
19 |
4. reiserfs broke down on all partitions that was using reiserfs |
20 |
5. reiserfs breaks down on 2.4.21+ and some older |
21 |
6. reiserfs breaks down on 2.6.17, ..18 and older that I can't remember |
22 |
7. ram, disks, cables was tested, changed, and problem stays |
23 |
8. ...sata, ata/pata |
24 |
9. maybe those are just accidents but they occur too often to call them just |
25 |
accidents |
26 |
|
27 |
Conclusions: |
28 |
1. UPS will not help you with reiserfs |
29 |
2. Do not use reiserfs on production systems |
30 |
3. "quite stable" means "works for them, not for me". |
31 |
4. journal only slows things down and does not preserve any consistency |
32 |
|
33 |
My questions: |
34 |
1. Is there the file system that preserves data & metadata like UFS2 ???? |
35 |
"solid as rock!" |
36 |
2. What options do I need to enable (mount/mkfs) for XFS or JFS to enable |
37 |
FULL journaling? |
38 |
3. How to bypass limit od 32000 dirs on ext3? |
39 |
4. Is there an option in kernel and how to enable it to sync on Oops and |
40 |
reboot? |
