DROBO DASHBOARD DRIVE SAYS GOOD BUT RED OUTLINE UPGRADE

I have very briefly looked at the alternatives listed in the OP and look forward to reading what other reader's experiences are like with them. Downtime hasn't been too bad overall now we know what to look for we have alarming and stuff set up so we can catch failures a little bit sooner before things spiral out of control. So far this has JUST been not annoying enough for us to look at alternatives. At that point the node pretty much becomes worthless and needs to be rebooted, which seems to fix the problem (there might be other less drastic measures but this seems to be all we have at the moment). Unfortunately we have had several problems where something happens to the node and it seems to lose contact with the filesystem or something. The 'working normally' aspect is most of the time everything is relatively seamless - we add new content to our servers using a variety of techniques (HTTP uploads, FTP uploads, etc) and they are all magically distributed to the nodes. Overall from my perspective, I would rate it as 'satisfactory'. I'm like a product manager type, so I only really see two sides of it: 1) when it is working normally and everything is fine 2) when it stops working and everything is broken. Now, I am not a sysadmin so can't comment on that aspect. We have been using OCFS (Oracle Cluster File System) for some time in production between a few different servers. 'Has anybody here on Slashdot had any experience with one or more of these clustered file systems? Are there any bandwidth and/or latency comparisons between them? Has anyone experienced a failure and can share their experience with the ease of recovery? Does anyone have any recommendations and why?'

And lastly it should require as minimal hardware as possible with the possibility of upgrading and scaling without taking down data.' The cluster filesystem should work well with hosting virtual machines in a high-available fashion thereby supporting guest migrations. If possible, I would like to control the number of replications at a file level. 'I really would like a clustered filesystem with distributed, replicated, and striped capabilities.

'Ceph seems the smallest of the three projects, but has an interesting striping and replication block-level driver called Rados.' It is much less complex and supports distributed replication and directly exporting volumes through CIFS, but doesn't quite have the same endorsement as Lustre.'

'GlusterFS seems to be gaining a lot of momentum now having backing from Red Hat. Right now I would like to reduce my hardware requirements to 2 servers total with an equal number of disks to serve as both filesystem cluster servers and KVM hosts.' Fortunately the creator seems to have Lustre back under control via his company Whamcloud, but I am still reticent to pick something once affiliated with Oracle and it also appears that the solution may be a bit more complex than I need. 'Lustre is well accepted and used in 7 of the top 10 supercomputers in the world, but it has been sullied by the buy-off of Sun to Oracle. Read on for the rest of Dishwasha's question. My research has yielded 3 possible solutions: Luster, GlusterFS, and Ceph.' I currently have 8TB of data (16TB raw storage) and am very paranoid about data loss.

I would like to upgrade the hardware but am currently severely tied to the current RAID hardware and would like to take a more hardware agnostic approach by utilizing a cluster filesystem. Now, I run RAID-10 manually verifying that each mirrored pair is properly distributed across each enclosure. I have suffered twice through complete loss of data once due to accidentally not re-enabling the notification on my hardware RAID and having an array power supply fail and the RAID controller was unable to recover half of the entire array. Dishwasha writes 'For over a decade I have had arrays of 10-20 disks providing larger than normal storage at home.
