Hi,
I have successfully created dedicated ZFS volume for dump
device and activated it using dumpadm(1M) command:
# zfs create -b 131072 -V 2048m data/dump
# dumpadm -n -d /dev/zvol/dsk/data/dump
Dump content: kernel pages
Dump device: /dev/zvol/dsk/data/dump (dedicated)
Savecore directory: /var/crash/tia
Savecore enabled: no
Now I would like to destroy ZFS pool "data", but I am not sure,
how I might release the dump device - "zpool destroy" as well
as "zfs destroy" complain in following way:
# zpool destroy -f data
cannot remove device links for 'data/dump': dataset is busy
# zfs destroy -f data/dump
cannot remove device links for 'data/dump': dataset is busy
I have looked at dumpadm(1M) manpage, but haven't found
similar approach I used for swap(1M) - I was able to release
swap ZFS volume using "swap -d".
Is there any way to release dump ZFS volume after it was
activated by dumpadm(1M) command ?
Thank you,
Jan
