Hi, we're running DPM2012R2U UR6 off a W2012R2 server.
We're trying to backup a clustered file server running W2008R2 with FC attached SAN volumes. After every volume DPM backups the server goes into a BSOD. Debugging shows me:
BugCheck 1000007E, {ffffffffc0000005, fffff80001c90b10, fffff880023b4e28, fffff880023b4680}
Probably caused by : volsnap.sys ( volsnap!VspQueryNtfsFreeSpaceBitmap+2fb )
Googling around tells me it's not supporting volumes larger than 64TB (none of ours are larger than 10TB).
Anyone got any ideas?! I've crashed the file server 6 times the last 12 hours and reaaaally don't want them to crash anymore :)
volsnap.sys is now at v6.1.7601.21854 after I tried to apply a hotfix that seemed to be related. (KB2627052)
Edit: Actually this only happens when an iSCSI volume is attached to the server - and this volume IS larger than 64TB though it's not apart of the protection group and thus...
This might be the wrong forum for this - but it's only happening now when we've introduced DPM to the system.
