Author is exaggerating. We recover 6 TB RAID-5 on desktop-class hardware 
in less then 6 hours. Our RAID is controlled by LSR (Linux Software 
RAID). Performance is not good while rebuilding a single node, but 
GlusterFS replicate/distribute translators help.

Consider this - a rebuild of 1.5-2 TB HDD in raid5/6 array can easily
take up to few days to complete. At that moment your storage at that
node will not perform well. I read a week ago very good article with
research of this area, only thing it's in russian, but it mentions a
few english sources too. Maybe google translate will help.
Here's the original link: http://habrahabr.ru/blogs/hardware/78311/
Here's the google translate version:

Larry & All,

I would much rather rebuild a bad drive with a raid controller then
have to wait for Gluster to do it.  With a large number of files doing
a ls -aglR can take weeks.  Also you don't NEED enterprise drives with
a raid controller, i use desktop 1.5tb Seagate drives which happy as a
clam on a 3ware SAS card under a SAS expander.

[Gluster-users] quota question

[Konstantin Sharlaimov]

Same here. We are evaluating GlusterFS as a backend for our elastic 
storage service, however it is a must that we limit amount of space our 
customers can consume. User or directory-level quotas would fit our 
needs perfectly.

Any chances quota support would be implemented in near future?

Regards,
Konstantin

I have a perfect use case for gluster, with one exception - I need quotas since 
people are paying for a given amount of capacity. Are user/group/directory 
quotas currently possible with gluster?

Thanks!
