I/O problem

Post by Admin » 11 Jul 2007, 16:37

I'm currently rebuilding the RAID array. This uses some I/O and has impact on the mail server. Currently TrashMail has more incoming emails than it could process. I'm currently fixing the problem...

Again I/O problems due of the huge amounts of spam flooding. The RAID rebuild should be finished this night.
Tomorrow all should be re-run fine (I hope).

I retuned now the system. It should now be at least 1000 times faster! :D

The RAID system has been rebuild to 100%. The I/O cache is now active again. The system should work now at fullspeed. :D

So these problems were caused by new RAID system being installed or disk crashing from current raid system?

What kind of RAID you use? RAID 5 because rebuild was so slow?

The RAID had the problem that I got a disk device error: One drive did not responded to a request. Then I rebuilded the RAID for security reasons. Its a 3ware RAID. At the same time I got very many spam emails from different sources (some marketing companies). The I/O was too slow to handle all request in the mail queue. But the problem is now fixed.
