Re: image map failed

Next step is check status for ceph (ceph status). If there is issues with OSD/placement, IO may hang indefinitely.

If HEALTH_OK, try reduce pool min_size (ceph osd pool set data min_size 1), and retry.

data_01

network connectivity is fine as per icmp output, is there any other way I can confirm this?

What did

sudo rbd -p data ls

show?

If it freezes too, issue is with pool itself (ceph health) or network connectivity.

Hi,

Thank you for the response but with sudo all it does is freeze:

rbd map data_01 --pool data

cluster-admin@nodeB:~/.ssh/ceph-cluster$ date && sudo rbd map data_01 --pool data && date

Hi,

Will someone please assist, I am new to cepph and I am trying to map image and this happens:

cluster-admin@nodeB:~/.ssh/ceph-cluster$ rbd map data_01 --pool data
rbd: sysfs write failed
In some cases useful info is found in syslog - try "dmesg | tail" or so.
rbd: map failed: (13) Permission denied

If someone could help it would be great
