Hey guys and girls,
I just started out a new job as a sysadmin for a company that uses 3pars. I never worked with them, but I'm starting to learn really fast, and I am already growing quite fond of 3par.
I currently have an issue with one of our 8200's. Apparently there was no monitoring in place, so nobody saw the issue before it was too late.
Short story: cpg full, volume read-only, and no way to fix.
Long storage: We have a pool with 46x6TB NL disks, with a raid6 CPG on top of that (178TB max usable). On that CPG are 15 x 16TB volumes (thin provisioned) that are used by a single Windows VM. Using windows storage spaces those 15 volumes are aggregated into a single 240TB volume used by a file server. Nobody thought about the thin provisioning, until the file server filled up, and then the 178TB limit was hit..
I see two possible paths to get out of this situation: 1. remove data and shrink, 2. add disks.
Option 1: We want to remove data again, but we can't. Since one of the VV's is in the failed state (it cannot allocate from the CPG), the volume is reported to Windows in the failed state, and is read-only. So we cannot remove any data from the volume
Option 2, adding disks, is the best idea of course. But according to our supplier, HPE will take 3-4 weeks to deliver some disks (!).
One of the idea's I'm playing with, is buying two disks from ebay (pn 823123-001), to have the problem fixed within a week and then replacing them when the original new hp disks arrive.
Is this a possibility? Can I just plug in any compatible disk and will it work? Or will I run into licensing issues and such?
