lvm broken with lvconvert --repair shows insufficient free space

[Linyu]

Hi forum,
I am suffering in a problem due to a system crash, I am using LVM-THIN created in proxmox GUI, the lvm seems broken and I saw it needs to fix manually in system log, so I try to use

lvconvert --repair data/data

to repair it, but it tells:

Volume group "data" has insufficient free space (128 extents): 4048 required.

More info:

It seems that the proxmox will use all space in a volume group to create a thin-pool, so here is the problem, I don't know how to fix it, now all the lv is inactive, any help?

I've added a disk to vgextend the vg, after lvconvert --repair data/data, I can see some lv is active now, but beyond that, I got this error :

root@cn-hk1:/dev/mapper# lvchange -ay /dev/data/vm-917065-disk-0
device-mapper: reload ioctl on  (253:4) failed: No data available
