I have Exchange 2010 running off a virtual machine hosted on Win2k8-R2
Hyperv. VHD file size was set to 127GB.
A couple of days ago, external mailflow stopped working. We identified that
the diskspace was running low 5GB free only and that the transaction logs
were taking up approximately 55GB of diskspace.
I initiated a Windows backup, but the conisitency check showing in progress
for over 6 hours. It was probably stuck due to no diskspace but oddly enough
no error message.
I killed the backup at that point. Expanded the HD drive space from HyperV
to 175GB, restarted the Exchange 2010 VM and initiated the backup again to
clear up the transaction logs.
It seems that the backup utility cannot get past the consistency check. It
just keeps going and going. Any idea if there a log I can check to see what
is going on?
