Hi, I'm trying to setup containers with LVM. I choose LVM over other options (ZFS or btrfs) becuase of some difficulties getting those working on my arm64 device and over Directory becuase I needed COW features. I'm using Ubuntu 16.04 with the LXD version from the Ubuntu repo (currently 2.0.5).
I have setup my VG but when I try and create a container, I get the following error: "Error Creating LVM LV for new image: Could not create thin LV named..." Firstly, I tried with out creating a LV as the storage-backends.md <https://github.com/lxc/lxd/blob/master/doc/storage-backends.md> says the LV will be automatically created. I configured LXD to point to my mg: $ sudo lxc config show config: storage.lvm_vg_name: lxdfs storage.lvm_volume_size: 1GiB $ sudo vgdisplay --- Volume group --- VG Name lxdfs System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 23 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 2.00 GiB PE Size 4.00 MiB Total PE 511 Alloc PE / Size 0 / 0 Free PE / Size 511 / 2.00 GiB VG UUID Bfv4Sv-JIej-Dfwj-1z96-0gFp-BcRe-F0v4dJ $ sudo lvdisplay $ sudo lxc launch images:ubuntu/xenial/arm64 u1604 Creating u1604 Retrieving image: 100% error: Error Creating LVM LV for new image: Error creating LVM thin pool: Could not create LVM thin pool named LXDPool $ So, then I thought maybe I needed to create the LXDPool, so I did. $ sudo lvcreate -l 50%Free -T lxdfs/LXDPool Logical volume "LXDPool" created. $ sudo lvdisplay --- Logical volume --- LV Name LXDPool VG Name lxdfs LV UUID 9fILN5-sOFu-Qm6k-9I1f-rfRG-4N1L-ECKT42 LV Write Access read/write LV Creation host, time igswmcmmas04, 2016-10-21 15:36:36 +0000 LV Pool metadata LXDPool_tmeta LV Pool data LXDPool_tdata LV Status available # open 0 LV Size 1012.00 MiB Allocated pool data 0.00% Allocated metadata 0.88% Current LE 253 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 254:2 $ sudo lxc launch images:ubuntu/xenial/arm64 u1604 Creating u1604 Retrieving image: 100% error: Error Creating LVM LV for new image: Could not create thin LV named dcae3165be4fb369d8e5b27b6f578ae7d889d1a7ad57d4b57587fb02099ff3f1 $ So, both ways I've had no luck. I tried a few other combinations and searched around but haven't found a solution. Any advice on what to try next? Thank you, Kyle
