cbuf

Saving the debug print buffer

Starting from version zfswin-2.2.6rc2 the cbuf can be more easily saved from a running system, to assist with debugging.

Open up regedit.exe, and navigate to:

 \HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\OpenZFS

Here there is now a entry called

 zfs_cbuf_save

Modify it by writing a "1" (one) to it, which will trigger a save. Use F5 to refresh Regedit in case there is an error message.

The file will be written to:

 C:\Program Files\OpenZFS On Windows\cbuf.txt

If the installer was used, this directory should already exist. Otherwise, create it by hand.
