I've been asked to elaborate on the issues that I had with
the raid cards.
this was all with RH 9, and mysql 4.1.x
The server is generic with a Supermicro X5DPE motherboard,
4GB RAM and 4 x Maxtor 250GB SATA drives.
The first server had the 3ware 8506 series card.
Shortly after it arrived, I got the error that the array was degraded.
So I tried a rebuild.
No Luck.
I replaced the drive and THEn did a rebuild.
Worked....for 2 days than went south again.
I returned that server to the mfg and the sent a new one with the adaptec SATA
raid card.
The machine started just fine.
Then I upgraded the database and perl (just like last time).
Everything was fine for about a week to 10 days.
In the middle of a huge upload, I saw that error about a degraded array,
again.
I had to wait for the database load to finish (which took another 10 days, but
that's another story).
After the db load finished, I used the CLIU to start a rebuild. Everything
looked fine and I left the job run overnight.
The next day, there were tons of errors on the screen (which, of course I did
not capture) but the end result is that a second drive had failed according
to the messages and that was that - everything was gone.
