[root@server3 ~]# vitastor-cli ls NAME POOL SIZE FLAGS PARENT testimg ecpool 10 G - [root@server3 ~]# vitastor-cli df NAME SCHEME PGS TOTAL USED AVAILABLE USED% EFFICIENCY 0 B 0 B 0 B 100% 0% ecpool EC 2+2 256 2 T 0 B 2 T 0% 100%

when I first run:

etcdctl --endpoints=... put /vitastor/config/pools '{"1":{"name":"testpool", "scheme":"replicated","pg_size":2,"pg_minsize":1,"pg_count":256,"failure_domain":"host"}}'

then run:

etcdctl --endpoints=... put /vitastor/config/pools '{"2":{"name":"ecpool", "scheme":"ec","pg_size":4,"parity_chunks":2,"pg_minsize":2,"pg_count":256,"failure_domain":"host"}}'

change the /vitastor/config/pools and then vitastor-cli ls occurs aborted

Hi Use vitastor-cli rm to delete an image Also do you understand etcdctl --endpoints=... put /vitastor/config/pools ... correctly? If you wanted to add pool with ID 2 you should've run

etcdctl --endpoints=... put /vitastor/config/pools '{"1":{"name":"testpool","scheme":"replicated","pg_size":2,"pg_minsize":1,"pg_count":256,"failure_domain":"host"},"2":{"name":"ecpool","scheme":"ec","pg_size":4,"parity_chunks":2,"pg_minsize":2,"pg_count":256,"failure_domain":"host"}}'

I.e you should've included both pools in this key

[vitalif]

terminate called after throwing an instance of 'std::out_of_range' - what(): map::at - Aborted is probably caused by the fact that you dropped pool 1 configuration. It shouldn't die with an exception in this case though, so I'll check it

thanks. vitastor-cli rm is ok.

I didn't understand the meaning of the [] parameter before. vitastor-cli rm [] [--writers-stopped]

test records:

[root@server3 vitastor-0.9.3]# vitastor-cli create -s 10G testimg55 Image testimg55 created [root@server3 vitastor-0.9.3]# vitastor-cli ls terminate called after throwing an instance of 'std::out_of_range' what(): map::at Aborted [root@server3 vitastor-0.9.3]# vitastor-cli ls -p 1 NAME SIZE FLAGS PARENT testimg2 10 G - testimg55 10 G - [root@server3 vitastor-0.9.3]# vitastor-cli ls -p 1 NAME SIZE FLAGS PARENT testimg2 10 G - testimg55 10 G - [root@server3 vitastor-0.9.3]# vitastor-cli rm testimg55 Done, inode 2 from pool 1 removed Layer testimg55 deleted [root@server3 vitastor-0.9.3]# vitastor-cli ls -p 1 NAME SIZE FLAGS PARENT testimg2 10 G -

The reason may be related to the following：

[root@server3 ~]# ll /dev/vitastor/ lrwxrwxrwx. 1 root root 7 Jul 12 15:19 osd1-data -> ../dm-9 lrwxrwxrwx. 1 root root 8 Jul 12 15:19 osd2-data -> ../dm-10

etcdctl --endpoints=51.32.27.7:2379 put /vitastor/config/pools '{"2":{"name":"ecpool", "scheme":"ec","pg_size":4,"parity_chunks":2,"pg_minsize":2,"pg_count":256,"failure_domain":"host"}}'

[root@server3 ~]# etcdctl --endpoints=51.32.27.7:2379 get --prefix /vitastor/pg/state | wc -l 512 [root@server3 ~]# etcdctl --endpoints=51.32.27.7:2379 get --prefix /vitastor/pg/state | more /vitastor/pg/state/2/1 {"peers": [], "primary": 1, "state": ["incomplete"]} /vitastor/pg/state/2/10 {"peers": [], "primary": 1, "state": ["incomplete"]} /vitastor/pg/state/2/100 {"peers": [], "primary": 2, "state": ["incomplete"]} /vitastor/pg/state/2/101 {"peers": [], "primary": 1, "state": ["incomplete"]}

all of the PG state is incomplete

and I create an img:

vitastor-cli create -s 10G testimg

And finally, I change pool config to 1 etcdctl --endpoints=... put /vitastor/config/pools '{"1":{"name":"testpool", "scheme":"replicated","pg_size":2,"pg_minsize":1,"pg_count":256,"failure_domain":"host"}}'

Fixed that "aborted with map::at" in master

i also deal with it ok
