Woke up to 4 (count em ..4) messages, Host Disk 1...4. Checked on Qmanager app , 3 messages 1,2 &4 . Immediately followed byWarning 2021-08-02 06:33:40 admin 127.0.0.1 Storage & Snapshots Disk [Storage & Snapshots] Low drive speed detected for disk "Host: Disk 2". Check disk status.
I have 451+ with 4 drives.Information 2021-08-02 06:33:43 admin 127.0.0.1 Storage & Snapshots Disk [Storage & Snapshots] Finished weekly disk read performance test.
Checked on Web interface on a computer, 4 messages , in order 1..4
So:
- The Qmanager seems to be unreliable. It's not showing me log entries which exist
- Given the Co-incidence is timing, I 'm guessing it's related to the performance test
I see nothing on this board about this but I do see stuff on Reddit . So my current best guess is:
- Qmanager is unreliable. I cannot trust message therein
- The "Drive speed low" is not , as it sounds a message about the spin speed of the drive , but a performance measurement of the disk
- Yesterday was 1st of month and a Sunday. The logs suggest
- Sun 1st at 8am SMART scans complted with no problems (so I guess the drives are fine)
- Mon @ 2am Raid Scrubbing started
- Mon @ 3am Malware scanning started
- Mon @ 03:30 AM ... Storage & Snapshots Disk [Storage & Snapshots] [IHM] Started analyzing disk "Host: Disk 2". Analysis started by the system.
- Mon at 5:11 AM .... Disk [Storage & Snapshots] Uploaded disk analysis data. ... [last of 1,2,3 &4]
- Mon at 6:33 + The above message "low drive speed"
- Mon @ 06:33:43 Disk [Storage & Snapshots] Finished weekly disk read performance test.
- NOW 10am ...Raid scrubbing is still running
- Trim runs @ 2am on 2nd of each month
- Raid scrubbing runs at 2:15 on 2nd of months
- No regular filesystem check (probably ought to do this)
- weekly (weakly:-) disk performance test . Seems there's no GUI way to set the schedule for this
- In Summary (TL;DR) Buggy Qmanager, Poor wording of message (not drive speed but Raid performance) poor scheduling of various background jobs
