Hi folks
I can share with you my experience on setup a Raid 1 system.
I've done al lot of test with RH 5.2, Kernel 2.0.36 +
raid0145-121519998/01081999/01281999
I've tested my L.B. with 16-18 xterm open...with 12 users compiling 2.0.36
with Gimp working with a 1024*1024 image at 16Ml color (average load of
60/70%)
my Box crash ....frozen....._rebooting_ (yes...after starting Netscape!)
without leave any useful trace...
After 5 or 6 crashes ... I've found a solution
Only for curiosity I've upgraded X-Windows to last release XFree86
3.3.3....and magically NOW
my Linux Box WORK!!
On this condition I've done, for testing, like 8.700.000 scsi interrupt in
15h!!
Now my L.B is on production with 2.0.36+raid014512151998 (I think is more
stable than other!)
with swapfile out of Raid (I think is more stable!)
***************************
My Linux box:
- Supermicro P6DBE with one PentiumII 350
- 128 Mb ECC ( not recognized by the kernel 2.0.36 .....I need to use
append = "mem=128M"!!!!!)
- 2 Mylex FlashPoint KT950 (for HA)
- 2 IBM SCSI DDRS 34560 4.5Gb (one per channel)
- 1 HP SureStore Dat8i attached on the scsi host 1 with 1 of the disk
- 1 3Com 3C590
- 1 AT Expert@Play
My setup (it's not _exact_ because now I'm not at office!):
