Shadow copies causes server to hang ...

[Guest bkran]

As stated at the subject of the post I have a windows 2003 SBS SP2 server

which has the behabiour stated. When shadow copies are created the whole

system freezes, mouse keyboard not responding and users get disconnected from

file shares and exchange mailboxes. I reprodused the error by manually

creating a shadow copy so this is the case. I have to add that this server

had its disks replaced lately and from a total size of 150 GB it now has a

total of 900 GB disk space as its only partition. System was moved with the

use of an imaging software to the same hardware ( only the disks on the raid

controller changed ) so it basically had no problem with the change except

this. Still its used space is atm 145 GB. Its an older system ( P4 with a

server board, 4GB of ram ) but it doesnt have any applications installed

except a well know antivirus suite so this shouldn't a performance problem.

Any ideas ??

 

Thanks in advance

First of all thanks for your response. I read the articles you suggested but

still, none of them is the case. I have no problem with the creation of

shadow copies, this part is working fine. its just that the system is

non-responsive at that minute ..... For the moment I have changed the

schedule so the copies are created after hours so it doesn't affect the users

but still an open issue....

I've been experiencing this problem for months now. I have no answer

as of yet. Part of the problem is the size of our shadow copy -

500GB. We scheduled it to run twice a day, but once in a while, it

hangs up on us. I've isolated that it hangs especially badly when

people are copying large amounts of data to the server at the time it

runs. People get knocked off the network/mapped share. It causes

Outlook to freeze. Have you heard any other solutions?

 

One other thing - when someone is performing a search, and selecting

the large drive/folder, the system hangs as well. We've seen similar

behavior with Google Desktop. It might be a controller or I/O

problem, I'm not sure...
