Delete pool .rgw.bucket and objects within it

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Irek,

the default value of replication level in version firefly is 3, while in
version emperor is 2, this is reason to make my cluster unstable.
I have another issue:
the size of the folder omap of some osds is very big, it is at about 2GB -
8GB, is there any way to clean up this folder?

Best regards,
Thanh Tran
