comment Installing Centos onto server for first time
Please give the specific model and generation of HP ProLiant server that you're trying to use. Otherwise, this question is unanswerable.

comment How to get 2 servers under control (Red Hat Linux)
Hire a pro :) I love situations like this. But shouldn't this have been a consideration before the admin was fired? Usually hold severance in exchange for the admin's coöperation.

comment Server utilization and how to deal with datacenter failure
No, I'm saying that there's probably some need to factor in growth and additional capacity for unpredictable usage patterns. Something like 60% utilization seems healthier.

comment Server utilization and how to deal with datacenter failure
I don't think I'd want to run at 80% utilization under any circumstances.

comment Replace Raid 5 HDD with a non empty HDD
No detail on the actual hardware makes and models involved? Wouldn't that be useful information?

comment ZFS: how to replace disk that faulted while resilvering after another fault?
RAIDZ3 is complicated. ZFS almost always works better with mirrors. It sounds like these are cheap disks and that they're not connected to a backplane, but via individual SATA cables. Are you sure the hardware is healthy otherwise?

comment What could be wrong with our HP Proliant Server
You may have disk array corruption from the backplane failure. There's no guarantee that the data is okay. Try booting with a rescue CD to see if there's any structured data on the drive. When you start the system, does it tell you how many "Logical Drives" exist on the Smart Array?

No. The server is very old. I'm not sure what options you have right now.

Yes, it can be done.

comment What could be wrong with our HP Proliant Server
Because the RAID controller connects to the backplane via a 68-pin SCSI connector. Any issues reflected on the 80-pin SCA ports used by the drives would be backplane problems.

That seems low... Across 14 vdevs, right?

comment What is the maximum ProLiant DL580 G3 SCSI or SAS drive capacity, and are only HP drives permitted?
@HBruijn That model was actually released in 2005. I had one in production. It was quickly replaced a year later with the G4, which incorporated SAS/SATA drives. Regardless, there's no good reason to use one today.

comment Finding correct IOPS to set limit with ESXi 5.5u2 and vSphere
Can you provide some real details on the hardware involved? Disk, type, capacity, RAID controller, server specifications, etc?

comment Advice for building production 140 disk (420 TB) ZFS zpool
I could answer this, but your use case is very specific and unless you're familiar with the tuning needs of the ZFS setup, it makes sense for this to go down the path of paid advice.

I'll reply later. But please answer why you would only use EL6.5. You should be on 6.6 and planning 6.7.

comment Identify which drives belong to a specific HP RAID 5 Group
No. This is a mess. You won't be able to reassemble the RAID without the right disks.

Can you give more detail about what you're doing and why you need to do it this way?

comment Configure HP BL460c Gen9 with external iSCSI SAN
Interesting question. I almost never hear about boot-from-SAN anymore. Good luck.
