I am getting the following when trying to remove drive from pool;

[root@cossaboon kcossabo]# greyhole --going /var/hda/files/drives/drive4/gh 
Please use one of the following with the --going option:
  /var/hda/files/drives/drive1/gh
  /var/hda/files/drives/drive2/gh
  /var/hda/files/drives/drive4/gh
  /var/hda/files/drives/drive3/gh

I hope this is all the DIAG stuff needed, one command did end in an error

This table gives you the number of pending operations queued for the Greyhole daemon, per share.

Total             87834 + 0     + 0     = 87834

The following is the number of pending operations that the Greyhole daemon still needs to parse.
Until it does, the nature of those operations is unknown.
Spooled operations that have been parsed will be listed above and disappear from the count below.

I think I did something bad, when working through an issue

Drive4 is going bad, SMART is continuing to increase bad blocks, and is part of the pool.
Landing Zone had 80G to move, and is activity choosing Drive4

Around 2pm I issue the 'going' command, and got the please wait, then

Then at 7:30, giving up as files were still being written to Drive4 from landing zone, I went to the config page, and unchecked it from the pool

Mar 14 19:34:49 7 going:   Directory /var/hda/files/drives/drive4/gh is not part of the Greyhole storage pool anymore. The above file will not be counted as a valid file copy, but can be used to create a new valid copy.

So now I think I am out of sync?

Since it appears that the greyhole going command is using rsync, and no updates to files are being made (all file activities are new files), Can I Issue the Going command on a drive not in the pool, and have it try to recopy the files over?

No, you can't do a --going on a drive that is not in the pool.

What you should do is stop the Greyhole service: in the Amahi Dashboard, go in the Advanced > Servers page.
For Greyhole, uncheck the watchdog option, then stop the service.

At this point, issue the --going command.
Note that it might be impossible for GH to move some files if the drive is failing.

Once this is done, uncheck the drive from the Amahi Storage Pool page, and restart the Greyhole service, and re-check the watchdog option.

Not sure why this situation is occurring. This was a problem before v0.8.4 of GH, but it should have been fixed in that version. Since you're running 0.9.2, you should have that fix, and going drives should not be chosen as a target for new file copies... I'll re-open the bug in the GH bug tracker to verify what is wrong.
