Has anyone succesfully setup, and used CentOS as an iSCSI server? I'm trying to setup a server with 4x500GB HDD's, setup in RAID 10 to act as an iSCSI server for a virtualization project, but I can't find a decent howto on how to setup an iSCSI server using CentOS. I would like to setup something like Openfiler, but we also need todo some other stuff that OpenFiler doesn't

Hi, I would like to get some input from people who have used these options for mounting a remote server to a local server. Basically, I need to replicate / backup data from one server to another, but over the internet (i.e. insecure channels) Currently we have been mounting an SMB share over SSH, but it's got it's own set of problems. And I don't know if this is optimal, or if I

Has anyone here ran performance comparisons between NFS and iSCSI when using network storage for KVM based guests. Also which have people found to be easier for managing live migrates etc. Steve -- Steven Ellis - Bulletin.Net Inc - http://www.bulletin.net

Hello ! I was wondering if anyone has done any kind of benchmarks regarding having a NFS export or using ISCSI. If not, is there any idea in how to do those benchmarks. In my case I will us NFS or ISCSI to export some space to run a mysql server, oracle 10g and ordinary file share. At this point I have 3 iscsi "servers" and 3 isci clients, each one running one service. All the

This might be a stupid question, but here goes... Would adding, say, 4 4 or 8gb usb keys as a zil make enough of a difference for writes on an iscsi shared vol? I am finding reads are not too bad (40is mb/s over gige on 2 500gb drives stripped) but writes top out at about 10 and drop a lot lower... If I where to add a couple usb keys for zil, would it make a difference? Thanks. Sent from a

Hello, we are running Dovecot (2.2.13-12~deb8u1) on Debian stable. Configured with Mailbox++, IMAP, POP3, LMTPD, Managesieved, ACL. Mailboxes are on local 1.2TB RAID, it's about 5310 accounts. We are slowly getting out of space and we are considering to move Mailboxes onto Netapp disk array with two independent network connections. Are there some pitfalls? Not sure we should use NTP or

Hi, I just completed testing on using Gluster via it's NFS server in a XenServer environment. My comparison was iSCSI in the same environment. You can see the results at http://majentis.com/2011/09/21/xenserver-iscsi-and-glusterfsnfs/ Gerald

Hi, Has anyone ever actually implemented a replicating iSCSI SAN using CentOS? I saw directions here: http://wiki.centos.org/HowTos/Ha-Drbd It looks doable, but I am not the strongest linux person and would like to hear if anyone has tried and if there any caveats. Also, I noticed that these directions are for CentOS 5. Is it pretty much the same for CenOS 6? Lastly, this might sound crazy,
