OneFS 9.7 introduces support for parallel restriping jobs, and hence the removal of the restriping exclusion set and its associated restraints. Instead, up to three restriping jobs can run simultaneously, if desired. This can allow services like SmartPools tiering to continue unabated, even in degraded cluster situations, such as during a FlexProtect drive rebuild.
Off by default.
More than one restriping job to run in parallel to shorten the restriping job to meet business SLAs. Depending on the situation, IT team can set parallel restriping to improve restriping time.
For example, the following CLI command can be used to configure ‘Partial’ parallel restring support:
# isi job settings modify --parallel_restriper_mode=partial
Similarly, the Job Engine can be easily reverted to its default restripe exclusion set behavior, with only one restripe job permitted, as follows:
# isi job settings modify --parallel_restriper_mode=off
Setting | Description |
Off | Default: Legacy restripe exclusion set behavior, with only one restripe job permitted. |
Partial | FlexProtect/FlexProtectLin runs alone, but all other restripers can be run together. |
All | No restripe job exclusions. |
