This is what I got, eventhough I created it with > parted /dev/sdc mkpart ... There's your problem I think. In my first post, I *guessed* that type needed to be 86. I'm sure 83 is NG - that's a standard Linux part. With fdisk and it's variations, there is a command to change partition type. Do that and select the one that shows LVM 986 I think). Write and (possibly) reboot or sfdisk -R /dev/sdc (which re-reads the partition info. If it shows *LVM* as the type, do you pvcreate, vgcreate, etc. and I bet you are OK. > > > [root at frodo ~]# dd if=/dev/sdc2 of=/dev/null > 12747056+0 records in > 12747056+0 records out > > ** The above output is after letting dd running for few minutes; > after that I killed the process because I was afraid it will take > it too long. Yes. The purpose was to see that partition size is OK (doesn't run off end of device). If you add blksize= with 4096, 8192 or 16384 or ... it goes much faster. But I think no need now, it's your partition type I think. > > > Thank you for your help, Us n00bs have to stick together here! :-) > Itay > <snip sig stuff> HTH -- Bill -------------- next part -------------- A non-text attachment was scrubbed...
