Add some kind of going SMB Share feature #52

Closed nexeck closed 12 years ago

nexeck commented 12 years ago

Is it possible to add an option, to tell Greyhole that an SMB Share is going. Greyhole should stop managing files from this SMB Share, and should start to Copy all Files Back into the real SMB SHare Directory.

gboudreau commented 12 years ago

Yes, I had planned for this... Probably using a --unwind command. Example: greyhole --unwind Photos

sbocquet commented 12 years ago

Thanks, that option would be very helpful for us. Do you have any idea when it could be release ?

gboudreau commented 12 years ago

I have no schedule whatsoever for anything Greyhole-related. I work on it whenever I have time, and feel like doing something! Might be this weekend, or the next, or could be months away. I'll try to make it happen sooner rather than later!

gboudreau commented 12 years ago

FYI, this is probably how I'll implement it: https://github.com/gboudreau/Greyhole/wiki/RemoveShareFromPool

With a big 'du' of the share folders on all storage pool drives before it, in order to know how much free space you'd need in the shared folder for unwind to work. (I'll divide the total disk usage by the number of file copies in greyhole.conf. It's an approximation, but it should be pretty close.)

Thanks a lot :)

Hi Guillaume,

Any plan on supporting this feature ? That's the last feature we need to have a "full working" plugin. https://github.com/OMV-Plugins/openmediavault-greyhole/issues/4

Have a nice day, Greetings.

gboudreau commented 12 years ago

Yes, I will add that, but I can't know when. Like I said, I hope it will be soon... I'll try this am, but with the kids that will wake up, I don't know if I'll have time to finish it.

sbocquet commented 12 years ago

LOL ! Same problem here ;) My daughter is sleeping but don't know when she's going to wake up !!!

Take care of them ;)

Not enough space:

$ sudo greyhole --remove-share=TimeMachine
Will remove 'TimeMachine' share from the Greyhole storage pool, by moving all the data files inside this share to it's landing zone: /mnt/hdd2/TimeMachine_share_test
  Finding how much space is needed, and if you have enough... Please wait...
    Space needed: 505GB
    Free space: 217GB
Not enough free space available in /mnt/hdd2/TimeMachine_share_test. Aborting.
gboudreau commented 12 years ago

Unknown share:

$ sudo greyhole --remove-share TimeMachine
'TimeMachine' is not a known share.
If you removed it already from your Greyhole configuration, please re-add it, and retry.
Otherwise, please use one of the following share name:
  Backups
  Books
  CrashPlan
  Games
  gb
  Music
  Photos
  RecordedTV
  Software
  Videos
  VideosAttic

Worked:

$ sudo greyhole --remove-share TimeMachine
Will remove 'TimeMachine' share from the Greyhole storage pool, by moving all the data files inside this share to it's landing zone: /mnt/hdd2/TimeMachine_share_test
  Finding how much space is needed, and if you have enough... Please wait...
    Space needed: 11.0MB
    Free space: 217GB
  OK! Let's do this.
  Deleting symlinks from landing zone... Please wait...
    Done.
  Folder does not exist: /mnt/hdd0/gh/TimeMachine. Skipping.
  Folder does not exist: /mnt/hdd1/gh/TimeMachine. Skipping.
  Moving files from /mnt/hdd2/gh/TimeMachine into /mnt/hdd2/TimeMachine_share_test... Please wait...
    Done. Copied 3 files.
  Folder does not exist: /mnt/hdd3/gh/TimeMachine. Skipping.
  Moving files from /mnt/hdd4/gh/TimeMachine into /mnt/hdd2/TimeMachine_share_test... Please wait...

  Moving files from /mnt/hdd8/gh/TimeMachine into /mnt/hdd2/TimeMachine_share_test... Please wait...
    Done. Copied 0 files.
  Folder does not exist: /mnt/airport/gh/TimeMachine. Skipping.
All done. Copied 3 files.
You should now remove the Greyhole options from the [TimeMachine] share in your smb.conf.

Great job Guillaume.
