Oh thheo, its still set to write through and no read ahead... Will normal disk cache cause issues like this still? Sent from my Nexus 5 using Tapatalk

So now the server seems very quick and stable.. Although we're probably looking to upgrade the raid cards soon. For now I've set a cron job to set the disk cache on with every reboot. I realized that even though megacli kept reporting that it was enabled, it wasn't. Since we've taken one node...

No, this is 10 active disks. No spares. I have two disks out of raid so I can do the install on a separate disk and testing with an untaxed single disk. Sent from my Nexus 5 using Tapatalk

I reinstalled the entire server to test the hardware. Breaking the existing raid, used the latest version of proxmox if the older version was the issue Sent from my Nexus 5 using Tapatalk

I used the default proxmox 3.1. Ext3. Mounted the other disks using the regular mount command. Mount /Dev/sdx /var/lib/vz Sent from my Nexus 5 using Tapatalk

Wasn't sure if there was some sort of polling that would affect the disks. Anyhow I'm bringing down the server today so I'll be able to update firmware and break the raid. Sent from my Nexus 5 using Tapatalk

Would Time have any affect on this performance (detrimentally so?), time was off between nodes by 3 minutes. My test so far has been W2k8 install times, I tested this with *RAW format and it was pretty quick compared to *VMDK which was taking around 2 hours. Haven't re-tested with *VMDK with...

Yeah I know it does, that's why im worried about the performance! haha. Not in office now, but I can pull the data again when I go there. From a few posts up: ~# megaclisas-status-- Controller informations -- -- ID | Model c0 | PERC H310 Mini -- Arrays informations -- -- ID | Type | Size |...

Hey guys, i've been reading different threads on here relating to this and haven't found a definitive answer... without me taking the server out of production as of yet. Main issue is performance, i've moved other VMs off the server and now only host 3 Windows Boxes and 1 Linux FW. I've shutdown...
