vinfra service backup volume-params change
Modify volume parameters:
usage: vinfra service backup volume-params change [--tier {0,1,2,3}] [--encoding <M>+<N>] [--failure-domain {disk,host,rack,row,room}]
--tier {0,1,2,3}
- Storage tier
--encoding <M>+<N>
-
Storage erasure encoding mapping in the format:
M
: the number of data blocksN
: the number of parity blocks
--failure-domain {0,1,2,3,4}
- Storage failure domain
Example:
# vinfra service backup volume-params change --tier 1 --encoding 1+0 \ --failure-domain host +---------+--------------------------------------+ | Field | Value | +---------+--------------------------------------+ | task_id | 28ae19dc-51c9-49bf-bd93-51a763fa181b | +---------+--------------------------------------+
This command creates a task to change volume parameters of the backup cluster as follows:
- The storage tier to 1
- The erasure coding scheme to 1+0
- The failure domain to host
Task outcome:
# vinfra task show 28ae19dc-51c9-49bf-bd93-51a763fa181b +---------+--------------------------------------------------------+ | Field | Value | +---------+--------------------------------------------------------+ | details | | | name | backend.presentation.abgw.tasks.ChangeVolumeParamsTask | | result | | | state | success | | task_id | 28ae19dc-51c9-49bf-bd93-51a763fa181b | +---------+--------------------------------------------------------+
