Description of problem: when invoking "lvcreate -l 100%FREE -T vg/thin-pool", lvm should allocate all the free PE to the thin pool ( 1 PE for metadata, others for data block ). Version-Release number of selected component (if applicable): How reproducible: always Steps: # vgdisplay vg3 --- Volume group --- VG Name vg3 System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 1 VG Access read/write VG Status resizable MAX LV 0 Cur LV 0 Open LV 0 Max PV 0 Cur PV 1 Act PV 1 VG Size 1020.00 MiB PE Size 4.00 MiB Total PE 255 Alloc PE / Size 0 / 0 Free PE / Size 255 / 1020.00 MiB VG UUID X8FHfz-ezqW-FIaW-A0Dx-uPnX-bUPl-k3Meez #lvcreate -l 100%FREE -T vg3/pool Rounding up size to full physical extent 4.00 MiB Insufficient suitable allocatable extents for logical volume pool: 255 more required Actual results: "lvcreate -l 100%FREE -T vg3/pool" return error Expected results: should create 255 PE to the thin pool and 254 PE as the data block. Additional info:
The 100%FREE option works well to create a liner volume so should also work well to create the thin pool. [root@laker ~]# lvcreate -l 100%FREE -n vg3/lv Logical volume "lv" created [root@laker ~]# lvs vg3 LV VG Attr LSize Pool Origin Data% Move Log Copy% Convert lv vg3 -wi-a--- 1020.00m
please ignore '( 1 PE for metadata, others for data block )' in 'DESCRIPTION' field.
Yes, we ought to fix this one.
Is this still an issue in F18 Alpha1?

This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '18'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 18's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
