[Bug 177350] Re: pvresize can't shrink PVs
By default pvmove allocates extents on pvs OTHER than the one they are coming from. If you want to move extents around on the same PV, IIRC, you have to pass --alloc anywhere, and explicitly specify destination extents. At any rate, this isn't really a bug. It is by design that you can not reduce a pv below its last allocated extent. If extent fragmentation is a problem, lvm currently does not support auto defragmentation. So this is really a feature request. ** Changed in: lvm2 (Ubuntu) Importance: Undecided = Wishlist ** Changed in: lvm2 (Ubuntu) Status: New = Triaged ** Summary changed: - pvresize can't shrink PVs + pvresize should defrag pv if necessary to reduce its size -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/177350 Title: pvresize should defrag pv if necessary to reduce its size -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 177350] Re: pvresize can't shrink PVs
I'm reopening this, because I'm having the exact same problem as Paulo. I'm trying with Lucid 2.6.32-24-generic and LVM2 2.02.54-1ubuntu4. Is anyone willing to take a quick look at this and determine if it's something which can be fixed? ** Changed in: lvm2 (Ubuntu) Status: Invalid = New -- pvresize can't shrink PVs https://bugs.launchpad.net/bugs/177350 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

You should be able to use pvmove to move the offending physical extents within the pv.

[Bug 177350] Re: pvresize can't shrink PVs
Soren, I just tried this out and sadly am having no luck. I run 'pvmove -v /dev/sdf1' (sdf1 is my pv) and the result I get is: Finding volume group mermaid No extents available for allocation But clearly I have extents on the pv, as reported by pvdisplay: --- Physical volume --- PV Name /dev/sdf1 VG Name mermaid PV Size 931.51 GiB / not usable 3.19 MiB Allocatable yes PE Size 4.00 MiB Total PE 238466 Free PE 97497 Allocated PE 140969 PV UUID wGWKzs-Z1XJ-DFrd-jalf-0HOE-UM1x-V1GNZt So, that doesn't seem to work.

[Bug 177350] Re: pvresize can't shrink PVs
I should have also mentioned that my vg only has one pv in it. Perhaps this is compounding the problem - there is no other pv in the group to which I can move extents. But really all I want to do is coalesce the extents on the existing pv so that I can physically shrink it. -- pvresize can't shrink PVs https://bugs.launchpad.net/bugs/177350 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release?
