I have an existing Windows 10 system, but I am trialing Linux mint 22.3
in a VMWare virtual machine. I am looking at droppingW10 when I'm happy
with Linux. So far so good but I have an issue with GnuCash.
My data is still on the Windows drive. I have set up an auto mount for
launch. I can access the data on the windows share, but GnuCash wont let
me save changes back to the windows share.
This is the message:
[Attached image shows "GnuCash could not write to
/media/windows/data/Documents/Finances/Accounts and Budgets/GnuCash/2026
Accounts.gnucash. That database may be on a read-only file system, you
may not have write permission for the directory or your anti-virus
software is preventing this action."]
Can you create new files in the shared folder?
I don't use GnuCash in a VM but, with other applications running on an
Ubuntu Linux guest under VirtualBox on a Windows host, I have found that
files can be created in a shared folder on the Linux guest but then
can't be modified, giving a message implying the file is read-only.
Although my experience is with VirtualBox, it could be that something
similar can happen with VMware (presumably Workstation?). I don't know
what the cause of the problem is; perhaps some process on the Windows
host (maybe antivirus or other security software) holds a handle on the
file so that it can't be opened for writing.
I set permissions to 777, But when I look at the accounts file, I have
read/write, my group only has read-only.
What should the permissions be, and what would be the best way to set
them properly.
The underlying filesystem mounted at /media/windows/ (or maybe
/media/windows/data/ is the mount point) in the VM is still a Windows
filesystem, where permissions work very differently than on Linux. You
probably can't reliably change permissions from the Linux guest.
I'm not sure offhand how shared folders work with VMware. With
VirtualBox, a "Guest Additions" package needs to be installed in the
guest. Folders shared from the host are then mounted under /media/ as
being owned by root but with a "vboxsf" group having read/write
permissions (and no access for other users). The user account in the
guest needs to be added to that vboxsf group to be able to access the
folder at all.
Still on VirtualBox, there's an option when setting up a shared folder
in the VM settings to specify whether the folder is read-only or
read/write within the guest. Is there a similar option in VMware? Is
it set to read/write? On VirtualBox, the directory in the guest still
appears to have write permission for the vboxsf group, but attempting to
write to it fails with a "read-only file system" error. Perhaps VMware
more accurately reflects that via the group write bit if the share is
configured to be read-only, so check in VMware that the share is
configured to be writeable.
Do the files/directories appear as owned by the user you're logged in as
within the guest, and does that user have write permissions? If so, you
should be fine as far as the emulated Linux permissions go even if the
group doesn't have write permission. However, the filesystem still
might not actually allow writes (which is what seems to happen in my
case with VirtualBox).
Not sure how much any of that will help, given I have little experience
of VMware Workstation, but perhaps it will give some ideas of things to
look for...
