I may be having an issue with Greyhole where it's not pooling to 2 of 7 drives. I'm not sure why it isn't. I have my shares set up for 2 copies of each share, so it should be spreading copies of my files throughout the drives. It seems to be working on 5 of the drives, but the other two have nothing written to them. I am running Amahi 7.1 on Fedora 19 from the express disc, 64 bit.

Code: Select all

[root@galactica ~]# greyhole -s

Greyhole Statistics

  /var/hda/files/drives/drive1/gh:  1324G -     0G =  1256G +     0G =  1256G
  /var/hda/files/drives/drive2/gh:  1834G -   134G =  1606G +     2G =  1608G
  /var/hda/files/drives/drive3/gh:  1375G -     0G =  1305G +     0G =  1305G
  /var/hda/files/drives/drive4/gh:  1834G -   134G =  1606G +     1G =  1608G
  /var/hda/files/drives/drive5/gh:  1834G -   131G =  1609G +     1G =  1610G
  /var/hda/files/drives/drive6/gh:  1834G -   135G =  1606G +     0G =  1606G
  /var/hda/files/drives/drive7/gh:  1834G -   135G =  1606G +     1G =  1607G
                                   ==========================================
  Total:                           11867G -   669G = 10595G +     6G = 10601G

I've attached my greyhole.conf file and fstab file.

Thanks for any advise you can give me.

Do the 2 drives have the /gh directory on them?

Yeah, they are.

[root@galactica drive3]# pwd
/var/hda/files/drives/drive3
[root@galactica drive3]# ls
gh lost+found

[root@galactica drive1]# pwd
/var/hda/files/drives/drive1
[root@galactica drive1]# ls
gh lost+found
[root@galactica drive1]#

Not sure, but maybe the current drive algorithm never gets to those drives with only 2 copies. Remember 2 copies means only 1 copy plus the original.

#### Shares Settings ####
# Number of copies of each file you want Greyhole to keep, per Share.
# This is not the number of duplicates! 2 copies = 1 duplicate

Might try changing the number of copies or you can group drives you want files to be replicated to via the /etc/greyhole.conf file too.

## Storage Drive Selection Groups ###
# The groups you define here will be available to use in the
# drive_selection_algorithm option(s) below.
# The group names (OK, NEW, BROKEN, REMOTE in the example below) can be
# anything you'd like.

I presume you are running the latest version of hda-greyhole. If not, you can update via command line by doing:

Code: Select all

yum update hda-greyhole

Okay, problem solved. Err, not really a problem actually....

The greyhole algorithm that determines where to put data is based on most available drive space. Drives 1 & 3 in my case are smaller drives/partitions. Drive 1 is the bulk of my boot drive, minus the space for boot & such. Drive 3 is another 1.5 TB drive. The other drives are all 2 TB drives, so drives 1 & 3 won't start accumulating data until the free space on drives 2, 4-7 is less than or equal to the space available on drives 1 or 3.

Like the simple ones

Glad all is well now.
