Erratic shared folders

Reported by: ToddAndMargo Owned by:
Priority: major Component: shared folders
Version: VirtualBox 3.2.10 Keywords:

Host type: Linux

Description

Hi All,

Host: Motherboard: Supermicro X8SAX Processor: x5650 Memory: 24 GB OS: CentOS 5.5 x64

Guest: Windows Terminal Server 2003 x32, Service Pack 2

Backup software: Cobain Backup 10.1.1.816  http://www.cobian.se/cobianbackup.htm

VM: VBox 3.2.10 (VirtualBox-3.2-3.2.10_66523_rhel5-1.x86_64.rpm) VM networking: Bridged Networking

I am not able to backup files from my Windows 2003 server, x32, SP2 guest to my host's Shared Folder with Cobian Backup. The error message follows:

ERR 2010-10-22 22:00 Couldn't create the destination directory "\VBOXSVR\vm-backups\pro60 2010-10-22 22;00;27": The filename, directory name, or volume label syntax is incorrect

Please note the time time occurs so yo can look for the error in the log files.

Note that this behavior is erratic. Cobian worked perfectly two days in a row. Then Cobian failed the next two days. Then, the fifth day worked flawlessly. The guest is rebooted every night at 23:00.

I also have trouble dragging and dropping large files to my Shared Folders from my guest (slow).

I also looked through the Windows System error log and did not find a Delayed Write Failure, so this is not a duplicate of 7628. There were no entries concerning this bug in the system log, other than the volume show copy service starting normally, which is expected.

Please let me know if I can assist you with the resolution of this bug.

Many thanks, -T

Have a clue to the mystery. This frequent error happens when:

/usr/bin/VBoxManage --nologo list runningvms Does not show the guest with the shared folder problems.

And, when the various VBoxManage commands (guestcontrol, acpipowerbutton, poweroff) all return:

ERROR: The machine 'xxxx' does not have an open session Details: code VBOX_E_INVALID_SESSION_STATE (0x80bb000b), component Machine, interface IMachine, callee nsISupports Context: "OpenExistingSession(a->session, uuid)" at line 297 of file VBoxManageGuestCtrl.cpp

This bug is probably closely related to bug 7772.

Hope this helps, -T

This error just crashed a production level server. Seems that when Cobian can not backup due to this error, that Cobian's rotate feature won't prune the corrupted backups the next time through. And they grow and grow and grow. You eventually get 100% usage and you server goes down. This is critical. Please fix.
