Post subject: | System Tasks |
Hi, I'm wondering if someone can explain the following system tasks that I have noticed running on both of our V400's remove_expired_vvs check_slow_disk They both appear to run every hour, and we haven't noticed them running before so are wondering if these are regular system tasks or whether they are running as a consequence of anything we have done recently We have migrated about 6 VV per V400 between a NL CPG and a FC CPG so were wondering if this is anything to do with that? I've searched this forum and various others but can't seem to find any conclusive answer at the moment! |

They are system tasks and i see them running on my systems all the time. remove_expired_vvs = Removed volumes that has expired , you can set a expire date on volumes or snapshots and they will be removed with this task. And i think that the Check_slow_disk = Will check the IOPS on each drive and report back if they are not performing as they should. ( Might also have something to do with where the system will create chunklets to balance the system as it grows ) |
