Windows cbuf
From OpenZFS on OS X
Saving the debug print buffer[edit]
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.
