Description Robert Lanning 2012-06-16 01:36:50 EDT
Description of problem:
Need a COW for VM cloning.

Additional info:
This can be done, with the support of COW in the underlying filesystems.

If you use BTRFS for your bricks, then when a COW request hits a file, a link can be made at the destination brick for the new copy, then instigate a COW action on the local file.

Then a rebalance can finish the actual copy process to the real destination brick, in the background.
Comment 2 Kaleb KEITHLEY 2015-10-22 11:46:38 EDT
because of the large number of bugs filed against mainline version\ is ambiguous and about to be removed as a choice.

If you believe this is still a bug, please change the status back to NEW and choose the appropriate, applicable version for it.
