Thanks to Morgan Jones <mjones6@commnav.com> and Sydney Weinstein <syd@myxa.com>. Both confirmed that I can do what I thought I could. The one thing to be aware of is that growfs will lock the filesystem while growing (which is mentioned in the growfs manpage, along with a way to alleviate the problem using the -s flag). Original question below. Thanks very much, -Adam We have a machine with an A3500 attached. It has four LUNs mounted: c4t5d0s0 c4t5d1s0 c5t5d0s0 c5t5d1s0 Each is around 300GB. We just added another A3500, because we need bigger disk volumes. What I'd like to do is unmount the existing volumes, create DiskSuite metadevices out of them, and then create concats with the four new volumes, so we'd have: d10 = c4t5d0s0 + c8t5d0s0 d20 = c4t5d1s0 + c8t5d1s0 d30 = c5t5d0s0 + c9t5d0s0 d40 = c5t5d1s0 + c9t5d1s0 Then, I'd just growfs the volumes to be 600GB each. I'm pretty sure this should work. The main questionable part is whether taking the curret /dev/dsk/c4t5d0s0 (etc) and making metadevices out of them will somehow disrupt the data. I know that when we mirror root disks, we just create d0 with /dev/dsk/c0t0d0s0, and nothing bad happens, so I think this will work. Can anybody confirm that? I'd rather do it this way than have to copy the data from the original LUNs to metadevices made out of the new LUNs in the second unit -- that could take quite a while. Thanks very much, -Adam _______________________________________________ sunmanagers mailing list sunmanagers@sunmanagers.org http://www.sunmanagers.org/mailman/listinfo/sunmanagersReceived on Wed Apr 30 11:36:54 2003
