ReadyNas Pro and Xencloud/Xenserver
So I support my church afterhours and in the process of upgrading hardware/software and planning on going to xenserver/xencloud to handle the the new servers. Planning on going with sbs 2011 and we also have a couple of other servers linux based doing image management, etc. So I have been reading all weekend on NAS hardware and performance, while I realize that performance will not be as good as if the storage was native to the box, I am considering putting all of the Data pools on the nas, they will be connected to the same switch gig speeds and contemplating whether to go iscsi or nfs. Looking at the naspro 4 or maybe the naspro 6 and my preference would be to run in flexraid mode and run raid 10. Actually my preference would be to run Raid 10 + hotspare in the Naspro 6 but I can't see anywhere that this is supported at the moment. We are talking about small number of users 5-10, so I think performance would be acceptable unless someone can tell me otherwise. The other thing that I am trying to figure out is if I put all of my VM's on the NAS, what is the best way to back them up/replicate them to another NAS etc. I can shut the vm's down and perform snapshots, right now we do backups three times a week to a usb hard drive that is rotated offsite. What I am trying to figure out is what is the best way to achieve this, I was thinking of purchasing a readynas pro2 and use the replicate function but its not clear if I could schedule this to replicate only when the vm's are offline. If anyone has any suggestions/thoughts I would greatly appreciate the input, Thanks :)Massive I/O errors on virtual machine using shared NFS
I'm not sure what information you need but here's what I'm experiencing: Running Cpanel as a virtual machine under XenServer 6.2 and using a ReadyNAS 314 (Raid 10) as shared storage. ReadyNAS running firmware 6.1.8 A few days ago, Cpanel became unaccessible. When checking the console using Xencenter, I saw massive I/O errors. Rebooting the VM took me to maintenance mode (Centos 6.4) where I ran fsck. After fixing numerous errors, I rebooted and everything came back up normal with all mounts as RW. After about 4 or 5 hours, it went down again with I/O errors and fsck did not fix the problems. After rebooting the NAS and running fsck again, I was able to successfully boot the machine with drives in RW mode. This time it ran for about 12 hours before crashing. Long story short, this went on for two days and now fsck is not fixing the problem. In addition, when I mount one of the NAS NFS shares onto another Linux machine, I'm getting a "No space left on device" error when trying to copy between folders even though there is 1.2TB free space on the share. df -h shows: 192.168.50.67:/data/Backup 3.7T 2.5T 1.2T 67% /mnt/Backup For right now, I'm getting all of my files off of the shared NAS and putting them on local storage repositories? Thank you in advance for any suggestions, Dan
