Hello, is there a way to add a zfs dataset to a zone online? The only info I found is to configure the dataset in the zone via zonecfg then reboot the zone. I would like to be able to add new separated dataset for each new db''s I add in the zone and of course if I need to reboot the zone every time I have to add/remove a db, my users will not be very happy... The only option I found for the moment is to create 1 dataset for all the db''s but I have problems with that : * every db''s are writing on the same LUN''s (or at least, I don''t where are writing the db''s) * adding a LUN is not a problem but removing it is not (yet) possible * we would be able to move a db from 1 zone to another one : both zones need to be rebooted. other solution is to have 1 zone per db but having a zone for a small db (let say less than 5 GB) is not really the best way to do (lots of diskspace lost for the binaries of the zone itself & the db''s). thanks in advance!

I haven''t tried it but - from a global zone try to manually mount it
in a local zone patch (like /zones/my_zone/root/mnt/test). If it works
check if zoned is on for that dataset - if it''s not set it.
And of course add to zone config if you want it to be there after
reboot.

hello Robert, I already tried this :( When you mount the fs, you need to set the zoned param to off. If you mount the dataset and then set the zoned param to on, the mountpoint disappear :( Kind regards, Christophe This message posted from opensolaris.org
hello all, i have a similar problem - i am trying to add a zfs volume to a non-global zone without rebooting it. it is not practical to shutdown the application just to add one more raw device. is there a way to manually create the device files in /dev/zvol/... in the zone and make it aware of the change ? greetings, Stoyan This message posted from opensolaris.org

You might be able to just do the mknod in the global zone, but have it create the device in the non-global zone''s filesystem tree. Use the same numbers as the global zone''s device. -- Darren Dunham ddunham at taos.com Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
