Hi, My solaris storage hangs. I login to the console and there is messages[1] display on the console. I can''t login into the console and seems the IO is totally blocked. The system is solaris 10u8 on Dell R710 with disk array Dell MD3000. 2 HBA cable connect the server and MD3000. The symptom is random. It is very appreciated if any one can help me out.

I am having problems when using a Dell PowerVault MD3000 with multipath from a Dell PowerEdge 1950. I have 2 cables connected and mount the partition on the DAS Array. I am using RHEL 4.4 with RHCS and a two node cluster. Only one node is "Active" at a time, it creates a mount to the partition, and if there is an issue RHCS will fence the de...

I am in the process of completely overhauling the storage setup here and plan to go to glusterfs. The storage involved is 8x Coraid units, 2x JetStor and a Dell MD3000. The Coraid and JetStor are network connected via ATA over Ethernet & iSCSI. The disks are also being upgraded to 1TB in the process. I do plan to use unify to bring most if not all the storage together. My first question is that since these units are over 12TB after being RAIDed, shoul...

...ort question: xm migrate (live or not) fails even though either host is capable of running the VM. Error seems to be: "not a valid guest state file: pfn count read" Long question: I have two boxes (devvmdevvmhost1 and devvmhost2) running xen 3.0.3 (RHEL 5), they are attached to a Dell MD3000 unit for shared storage. I''m working on configuring live migration, and have set up a test VM (testwww). Storage is a single LVM partition on the MD3000. I can start the VM on either physical host (copied /etc/xen/testwww from devvmhost1 to devvmhost2) and it works fine (obviously only r...

We''re setting up ZFS in front of an MD3000i (and attached MD1000 expansion trays). The rule of thumb is to let ZFS manage all of the disks, so we wanted to expose each MD3000i spindle via a JBOD mode of some sort. Unfortunately, it doesn''t look like the MD3000i this (though this[1] post seems to reference an Enhanced JBOD mode......

I have a Dell PowerEdge 2950 and am looking to add more storage. I know a lot of factors can go into the type of answer given, but for present and future technology planning, should I look for a rack of SATA, SCSI, or fibre channel drives? Maybe I'm dating myself with fibre channel, and possibly SCSI? I may be looking to add a few TB now, and possibly more later. What are people

Hi, we would like to establish a small Lustre instance and for the OST planning to use standard Dell PE1950 servers (2x QuadCore + 16 GB Ram) and for the disk a JBOD (MD1000) steered by the PE1950 internal Raid controller (Raid-6). Any experience (good or bad) with such a config ? thanxs, Martin

Hi: I need advice on implementing a storage server. I really do not have the $ to spend for a Dell iSCSI storage divice and I am thinking trunning CentOS 5.x with ftp or FreeNAS. Here is what I am looking at and concerned about. Situation: My current storage needs are approximately 1.5 TB annually. This will increase to about 3.5 TB annually over the next 5 years (rough est.). This box

Hi, I just installed 2009.06 and found that compression isn''t enabled by default when filesystems are created. Does is make sense to have an RFE open for this? (I''ll open one tonight if need be.) We keep telling people to turn on compression. Are there any situations where turning on compression doesn''t make sense, like rpool/swap? what about rpool/dump? Thanks, ~~sa
