Did you disable SElinux on this machine? I do mean disable and not permissive mode.Originally Posted by crp
OK, two areas to reply to.
I have SElinux enabled on my machine. I have no problem disabling it, just curious as to why.Did you disable SElinux on this machine? I do mean disable and not permissive mode.
Well, the server that I have for this project has six hard drive bays; five of which are currently taken. I *might* be able to get a sixth matching drive, and I *might* be willing to give up the hot spare. We are certainly not going to replace all the existing drives with bigger drives at this time. We were considering using an EMC array, with more space, but that got shot down, at least for now, for budgetary reasons. As far as the 420 GB requirement, I based that off 400 users averaging a 1 GB per person. I think that is pretty fair. When we migrate our users over we may allow them to copy their existing email, currently stored on local .pst files, over. So the space could be used up pretty quickly.If you really can't get more drives and *must* stay at 420GB then you are stuck but as Bill warned RAID 5 is the worst config for our index and DB files. Lots of small writes and heavy random read traffic.
It sounds like I definitely need to dump the RAID 5. Assuming I can't get the additional drive would it be better to just configure the array as JBOD, and use LVM within Linux, or something like that?
Just letting you know, RAID 5 and Zimbra just don't mix well. Trust me, I went live with Zimbra on RAID 5 and wish I hadn't. We ended up switching everything to 0+1. Since then, performance is much better. Mail has not gotten behind in queue's and we have ~75,000 - 100,000 messages delivered inbound each day(that does not include internal mail processing). We also have 3 MTA's and 5 mailbox stores for our 23,000 users.
SELINUX=disabled on the server.
One client pc is old (700Mhz, NTWS4), so I am not too surprised about slow and poor performance.
The other one is running W2K SP4 on Celeron 2.2.6G with 256M RAM and 720M swap , using Firefox 2.
