I have two servers in cluster - MAIL1/ORG and MAIL2/ORG. Registration server - MAIL1/ORG

When I creating a replica of new user mail file (in background, during registration), I get an 'Attention Requred' - "Disk space statistics could not be found on Mail2/ORG", but replica on MAIL2/ORG created anyway

In MAIL2/ORG console

show stat disk

[0EEC:0007-11C8]   Disk.C.Free = 76 846 448 640
[0EEC:0007-11C8]   Disk.C.Size = 150 082 678 784
[0EEC:0007-11C8]   Disk.C.Type = NTFS
[0EEC:0007-11C8]   Disk.D.Free = 135 882 330 112
[0EEC:0007-11C8]   Disk.D.Size = 149 249 060 864
[0EEC:0007-11C8]   Disk.D.Type = NTFS
[0EEC:0007-11C8]   Disk.E.Free = 5,5954783314E+12
[0EEC:0007-11C8]   Disk.E.Size = 8,0003140116E+12
[0EEC:0007-11C8]   Disk.E.Type = NTFS
[0EEC:0007-11C8]   Disk.Fixed = 3
[0EEC:0007-11C8]   Disk.Remote = 0
[0EEC:0007-11C8]   11 statistics found

I'm not sure, but this notification about statistics appeared after 9.0.1FP8 IF4 installation on MAIL2/ORG. MAIL1/ORG still 9.0.1FP8 IF3

Any suggestions/ideas welcome.
