Buffer I/O error on dev dm-7... VM onlu readable

[marcinsm]

Hi,
I have a problem,
I dont have to create a new VM, i have error:
Aug 24 14:43:26 R610 pvedaemon[8997]: VM 102 creating disks failed
Aug 24 14:43:26 R610 pvedaemon[8997]: create failed - lvcreate 'pve/vm-102-disk-1' error: Cannot create new thin volume, free space in thin pool pve/data reached threshold.
Aug 24 14:43:26 R610 pvedaemon[8178]: <root@pam> end task UPID:R610:00002325:02FE9011:599EC9EE:qmcreate:102:root@pam: create failed - lvcreate 'pve/vm-102-disk-1' error:
Cannot create new thin volume, free space in thin pool pve/data reached threshold.

When I type a command lvs, I have this :

root@R610:/dev/pve# lvs
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert

vm-101-state-instalacja pve Vwi---tz-- 2.49g data

All my machines do not work well, they are only readable, I think this is the cause of the lack of space, but what

What should I do,
PLEASE HELP ME

your lvmthin metadata lv is full you should extend it
see https://pve.proxmox.com/wiki/LVM2#Resize_metadata_pool

Hmmmm
but which partition resizing ?

My skill i soo low so please help as the command looks like?
lvresize --poolmetadatasize +4G <VG>/<LVThin_pool>

When I using command lvdisplay :


--- Logical volume ---
LV Name data
VG Name pve
LV UUID jOl9bm-BRLK-12Sc-gUvX-lz7x-fxrZ-hS5Miv
LV Write Access read/write
LV Creation host, time proxmox, 2017-08-07 16:45:46 +0200
LV Pool metadata data_tmeta
LV Pool data data_tdata
LV Status available
# open 4
LV Size 1.89 TiB
Allocated pool data 7.25%
Allocated metadata 99.95%
Current LE 496695
Segments 1
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 253:4

<VG> is the VG Name ('pve' in your output)
<LVThin_pool> is the name of the thinpool ('data' in your output)

but i guess 4 GiB is more than necessary

OK thanks its works !
lvresize --poolmetadatasize + 4G /dev/mapper/pve-data
