b333z / zfs_slog_zero_vsalloc_inline.patch
Last active January 2, 2016 07:18
This Systemtap script is to provide a workaround with removal of slog device that fails due to vs_alloc for the device != 0. As a safely precaution ZFS refuses to remove the device. It basically implements a linux version of a workaround described here: http://zpool.org/2012/01/10/how-to-fix-a-stuck-zfs-log-device.
