Expanding array takes ages

Hi,

we have a Proliant ML530G2 with a Smart Array 532 controller with one array which contains 5 36Gb drives. I've added a 6th drive to it and am currently expanding the array. But this takes ages. It's been running for 1 day now and is only at 30% completion. Is this normal that it takes so long ?

Re: Expanding array takes ages

Hi,

Use ACU then select controller then setting it will tell you what is the rebuild proirty set by us on server. If it is low then it can take time i suppose.

Re: Expanding array takes ages

Hi,

I've already set it to 'high' when I started the expand process. Is it safe to reboot the server during the expand or not ?

Smart Array Controllers May Experience An Unsuccessful Rebuild Operation Under Certain Conditions


customer advisory EX030314_CW01 revision 1
released January 2004

description


Certain Smart Array Controllers and firmware versions may appear to complete a rebuild operation successfully on a ProLiant server, even though one or more disk blocks may not have been written successfully.

This most commonly occurs when a hard drive with uncorrectable media errors is initially failed (i.e., amber LED on hard drive tray illuminates) by the Smart Array Controller, and is then subsequently removed and reinserted, thereby initiating the rebuild process. The hard drive should again be failed by the Smart Array Controller; however, Smart Array Controllers using certain firmware versions may indicate that the rebuild operation completed successfully even though it did not.

Note: When Microsoft Exchange Server is running on the server, an Application Error 1018 may be generated by the Exchange Server as a result of the disk block(s) not being written successfully during the rebuild operation. However, an Application Error 1018 can be caused by several conditions, including slow transfer rates, slow device responses to relinquish the SCSI bus, or faulty hardware.


scope


Any ProLiant server configured with any of the following Smart Array Controllers and their respective firmware versions:

Smart Array 5300 Controller with Firmware Version 1.72 through Version 2.32
Smart Array 532, Smart Array 5i and Smart Array 5i Plus Controllers with Firmware Version 1.72 through Version 1.74
Smart Array 431 Controller with Firmware Version 1.18 through Version 1.22
Smart Array 4200 and Smart Array 4250ES Controllers with Firmware Version 1.44


resolution


To prevent an unsuccessful rebuild from occurring, update the Smart Array Controller firmware to the following versions using the appropriate Offline ROM Flash ROM Update Utility:

Re: Expanding array takes ages

Hi,

thanks for the info. The Smart Array controller has the latest firmware so that's not the issue. It's now at 48 percent rebuild after 48 hours.... Thus it will almost take 4 (!!!) days to expand the array....

Re: Expanding array takes ages

Franc,
I ran into the same thing and what I ended up doing was letting it rebuild one drive at a time. Of course, I did not have 6 drives, only 3, but it seemed to work for me.
Just my two cents worth!
Good luck,
Kelly

Re: Expanding array takes ages

Hi Kelly,

I'm not rebuilding, just expanding the array by plugging in an extra drive. Looks like it would be a lot faster to create an image of the server. Remove and recreate the array and then putting the image back. Then it was done in way less time than the four days it now takes.

Re: Expanding array takes ages

Hi,

well after four days the expanding finally completed. However, now I have additional space. But I want the additional space being added to the logical drive. So I extend the logical drive. It's been running for a day and it's only at 25%. Thus, in total, adding a 36Gb drive to a 5 disk raid 5 array takes 8 days to complete. Is this really normal ? I don't want to think if I need to add a 72Gb drive to our other server. That will probably take a month or so.

Re: Expanding array takes ages

It takes anywhere between 15 - 45 min per GB of the logical drive. Try putting the expand priority to high
There’s your problem!!! This thing is set to EVIL!
