similar to: Vsftpd & Iscsi - fast enough

Looking to cluster an FTP server. Right now we do a mix of stuff where we use a few separate servers linked through various hacks, that utilizes VSFTPd heavily for hundreds of television station news websites, where, of course, the current weather maps get uploaded from everywhere, all day, from NOAA and the like. I'd like to move from the current setup to something that's more HA

I''m trying to set up a iscsi connection (with MPXIO) between my Vista64 workstation and a ZFS storage machine running OpenSolaris 10 (forget the exact version). On the ZFS machines, I have two NICS. NIC #1 is 192.168.1.102, and NIC #2 is 192.168.2.102. The NICs are connected to two separate switches serving two separate IP spaces. On my Vista64 machine, I also have two NICs connected in

Hey everyone, Is anybody aware of a /true/ active/active multi-head and multi-target clustered iSCSI daemon? IE: Server 1: Hostname: host1.test.com IP Address: 10.0.0.1 Server 2: Hostname: host2.test.com IP Address: 10.0.0.2 Then they would utilize a CLVM disk between them, let's call that VG "disk" and then directly map each LUN (1,2,3,4,etc) to LV's named 1,2,3,4,... and

Just started messing with multipath against an iSCSI target with 4 nics. What should one expect as behavior when paths start failing? My lab setup was copying some data on a mounted block device when I dropped 3 of 4 paths and the responsiveness of the server completely tanked for several minutes. Is that still expected? Thanks, jlc

Sorry for the off-topic question but I need advice on a buying a ISCSI SAN for 4-6 servers running CentOS 4.4 .The main purpose for the SAN is to store email accounts (that will be accessed by imap - dovecot) and other documents. Minimal redundancy is required (e.g. dual power supplies, battery backed write cache or mirrored controllers) and price for a 2 TB configuration should be under $ 10000.

Hi anybody! I'm not shure if this really is a rsync problem, it might also be a shell issue. But hopefully, someone has a hint for me ;-) I'm using rsync 3.0.9 on two OS X Servers (FreeBSD) to synchronize several folders between both servers (2-way-sync). Works fine, with one exception: One of the directories to be sync'd contains a whitespace in its pathname, and this one only

Hi, I do have one iscsi storage with 4 GBit nics of which currently only one is configured with an ip and which is in productive use by one cent os 6.3 server. Doing some research brought me to the idea to use some nic bonding or multipathing for that storage, but multipathing I did about four or five years ago only once :) Furthormore I can't find the ultimate answer (may be there is not

Hi All, Need some information on getting the right storage array to buy for my cluster configuration can anyone help me with this my Setup so far 2 Athlon 2800 Sempron System 1 Wti Network power switch 1 24 Port 10/100 Cat5 switch 2 Adaptec 39160 scsi host adapter pci cards installed in the systems. I need to know what is the best storage solution with this configuration Thanks

Hi, We have patched Centos 4.4 to work properly with the recent DST changes, but our customers are reporting wrong FTP client timestamps based on which areas they live in. What are the two main mechanisms in Centos that control time? I know about /etc/localtime and TZDATA, is there something we may have missed? Or is this perhaps a VSFTPd thing and I could go bug that list? To be clear,

Greetings, I've hit this exact 'bug': https://bugzilla.redhat.com/show_bug.cgi?id=491311 I need to remove the mappings manually. I assume this is done via 'multipath -F' followed by a 'multipath -v2' ? Has anyone experienced doing this on a production system? We can do it during hours of low activity, but we would prefer to keep the databases on this host online at

If I execute these via command line, will they persist after a reboot? Or, should I be putting these into a file like /etc/sysctl.conf? --------------snip-------------- /sbin/sysctl -w net.ipv4.tcp_max_syn_backlog=2048 /sbin/sysctl -w net.ipv4.tcp_fin_timeout=30 /sbin/sysctl -w net.ipv4.tcp_keepalive_intvl=10 /sbin/sysctl -w net.ipv4.tcp_keepalive_probes=7 /sbin/sysctl -w

Hey I need to run some pgp commands, -what's the name of the package supported by Centos that will allow me to work with pgp? I need to run pgp --fingerprint key.name or it's equivalent. Pro question. Google searches didn't show much, tried to search for pgp, gnupg, openpgp, pgp on centos, openpgp on centos, centos/pgp. No worthy results came back. Any advice? -karlski

We are looking into the possibility of adding a dedicated ZIL and/or L2ARC devices to our pool. We are looking into getting 4 ? 32GB Intel X25-E SSD drives. Would this be a good solution to slow write speeds? We are currently sharing out different slices of the pool to windows servers using comstar and fibrechannel. We are currently getting around 300MB/sec performance with 70-100% disk busy.

Hello, I'm looking for test users for new iSCSI target software designed for multipath failover cluster nodes. I'm very interested in the virtual machine such as Hyper-V. So I'm also tuning the target for using VMs. I need an environmental report in particular other than FreeBSD 7.1 RELEASE p3 i386/PAE kernel w/ZFS. I welcome the report with other initiators below. If you are

Hi, We had received a new EMC storage (Clariion CX4) and the EMC analist has told us that CentOS aren't on their support list, but RHEL are :) Well anybody on the list has a CentOS host talking (iSCSI) with an EMC storage, preferably using the EMC Powerpath software, and can talk about you experience? Or I will need to buy some REHL licenses ? I'll put my hands on it only next

How does one configure a fence device in the form of a NIC card in centos 5? Is the gnbd item relevant to this? I have posted the question to linux-cluster also, but they are much less active overall, -so if you have info, massively appreciated... -karl

Hi list, CentOS 4.4 connecting to Promise M500i iSCSI disk array. 2/4 servers connect fine with iscsi-initiator-utils-4.0.3.0-4. The other 2 servers have this in dmesg: SCSI device sdb: 1 512-byte hdwr sectors (0 MB) sdb: asking for cache data failed sdb: assuming drive cache: write through SCSI device sdb: 1 512-byte hdwr sectors (0 MB) sdb: asking for cache data failed sdb: assuming drive

Hello, I?m using ZFS to export some iscsi targets for the virtual box iscsi initiator. It works ok if I try to install the guest OS manually. However, I?d like to be able to import my already prepared guest os vdi images into the iscsi devices but I can?t figure out how to do it. Each time I tried, I cannot boot. It only works if I save the manually installed guest os and re-instate the same

Anyone running centos with an iscsi filesystem mounted? If so: What version of centos? Which iscsi package? What filesystem are you using on the mount? Does it perform like you'd expect? Thanks, peter

Hi, I want to take snapshots of a iSCSI devices from a target that hasn't snapshot/cloning capabilities (it's a Infortrend A16E storage array). What method are you using to make snapshots/clones of iSCSI targets using Open-iSCSI + CentOS? What about using Open-iSCSI + LVM snapshots system? For example: - Take a LVM snapshot in the initiator with "lvcreate". - Give read-only
