Re: [CentOS] expand physical volume
I hope you meant, created a new partition and a new pv and then added that to the vg. /Peter Of course yes :-) Thomas ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] expand physical volume
Both fdisk and parted _can_ do it. But just as you've mentioned, parted has a nasty habbit of involving itself in the content of the partition... For lvm it really won't matter at all if your vg/lv is made up out of two partitions with pvs or just one. /Peter Hi, I created the second partition, added it to the pv and everything is working fine.

Re: [CentOS] expand physical volume
Note that I suggested that you _dont_ resize partitions but create a new one (new partition with a new pv on it etc.). pvresize resizes the pv _if_ the containing block device or partition has already been grown. parted seems to want to resize the file system also and i think this would make some troubles. I thought pvresize would do this in one step? Hi Peter, Thank you for all your suggestions! I will probably will add sdb2, but i would like to know if it is possible to resize a partitition without the filesystem an if yes how do i do that?

Re: [CentOS] expand physical volume
The one and only partition on your device (sdb1) has the old size. That is, there's free space on sdb. You have to either 1) create a partition sdb2 (and then a pv on it etc.) or 2) resize the partition sdb1 (then resize the pv etc.). I'd pick #1. remember to reread the partition table after creating the partition (partprobe /dev/sdb or similar) before doing pvcreate on sdb2. The all you have left is to add the pv to your vg, resize the lv (or create a new lv, whichever...). And finally resize the filesystem in the lv. Hi Peter, How do i resize this partition? parted seems to want to resize the file system also and i think this would make some troubles. I thought pvresize would do this in one step?

The one and only partition on your device (sdb1) has the old size. That is, there's free space on sdb. You have to either 1) create a partition sdb2 (and then a pv on it etc.) or 2) resize the partition sdb1 (then resize the pv etc.). I'd pick #1. remember to reread the partition table after creating the partition (partprobe /dev/sdb or similar) before doing pvcreate on sdb2. The all you have left is to add the pv to your vg, resize the lv (or create a new lv, whichever...). And finally resize the filesystem in the lv.

[CentOS] expand physical volume
Hi. I added a disk to a hardware raid 5 array and now i want to expand the LVM physical volume. There are now 4 sas 146GB disks in the server. The virtual disk /dev/sdb from the raid controller has been resized successfully with the server management software osma.
