I'm getting pages & pages of these two minor errors, can I correct this or resolve this problem?

This version of myMain also fixes the HDIO_GET_IDENTITY messages in the log.  These seem harmless, but I believe that each one causes the drive to spin up and immediately get spun down by unRAID.  This happens so fast you can’t see it, but is the equivalent of starting and stopping your car over and over again for no reason.  The only time you should see such messages is if your cache drive is on the SAS controller.  For that reason, it is advisable to NOT have your cache disk on the SAS controller.  (You can also get this message if non-array disks - like disks you are preclearing - are on the SAS controller.  The HDIO errors are not a big deal if you are preclearing, because the disk is already spinning and it does not get spun down.)

Thx mbryanr

I am pre clearing two 2TB drives right now for about 24 hours. hence all those 000,s of messages in syslog. I cannot tell exactly how long I have been clearing the hdd's for as my server time seem to have gone nuts. On the preclear screen it says  Elapsed time 3624:32:35, on unMENU it say my last Parity check was 151 days ago.. (was actually yesterday )and on my Tower main screen i cannot see the time because unRAID has decided to do a full format my WD 750GB HDD even though it has been pre cleared!! It has been formatting now for around 4-5 hours. Best just to let it all chug away overnight whilst I'm at work and see what's happening when i come home in the morning.

Steps 1-10 complete / done

Post read on both 2TB drives 58% complete. avg 80 MB/s on both drives.

 

version: 4.5.6

A disk that has been pre-cleared will still need to be formatted... clearing is NOT formatting.

Formatting should only take a minute or two even with large drives.

If it says it is "Formatting" and it has been 4 or 5 hours something is wrong.  Examine your syslog.  You'll probably find lots of errors.

If it is clearing the drive, then the pre-clear was not successful. (or you formatted it yourself thinking it would help, which erased the pre-clear signature.)

I'm aware of that Joe.L, but the last 9 drives I have cleared / filled with 0's have formatted in a few minutes.

I used the preclear script to clear all my drives and the drives were attached to my unRAID server during the process and remained on the same sata port when I assigned and hit yes button for formatting.

Just before I left for work I was unable to connect to unMENU but could connect to unRAID menu. Drive 10 is still showing as formatting and when I select the refresh button the session refreshes but nothing changes. I am able to select other tabs to view so the session does not appear to be frozen. I have two sessions open on telnet still preclearing the two 2TB drives. They should be complete when i get home. Can I reboot my server from a telnet session? I would prefer not to do a hard reset if possible.

Everything seemed to go tits up when I assigned and started formating the WD HDD.

The drive precleared okay and there were no errors, it took 11 hours to clear. Which is about where i would expect it to be.

Yes you can reboot from telnet.

 

As long as you have nothing else running that would keep a disk "busy" you can just type

powerdown

at the command prompt to have it power down.  That may or may not work, depending on if emhttp is listening for it. 

 

If you would rather you can type the commands individually as in this sequence

/root/samba stop

umount /mnt/disk1

umount /mnt/disk2

umount /mnt/disk3

      (do this for each disk in turn)

      then... once all the disks are un-mounted

/root/mdcmd stop

 

if it responds OK you've cleanly shut down.

You can then reboot by typing

reboot

 

 

Thanks Joe.L

I could not get disk6 to shut down so I had to do a soft reboot on my server and another parity check

If you could not get disk6 to un-mount then you had a program accessing that disk, or a file on it, or it was the "current" directory for a process.
