Every weekend I do backups of all CT which take a lot of IO. It didn't affect much load average before 108 but as soon as I upgraded to 113, load got very high and nodes became sluggish during backups. It might be something else but I was looking for feedback if someone else had the same issue. I will continue to troubleshoot this issue. Meanwhile, I will upgrade them from 113.12 to 113.21 and see how it goes even if there's nothing related to this in the changelog.
See smartctl - temperature of HDDs and seek/read errors. Reason of "nodes became sluggish during backups" can be high HDD temp and high seek/read errors rate. Also see free space on backup partition - if free space low it will be very fragmented and write will be slow - need many IOPS for write many small file chunks. -- Best regards, Gena _______________________________________________ Users mailing list [email protected] https://lists.openvz.org/mailman/listinfo/users
