Thanks for the reply. We will mainly use this for archival - near-cold storage. Anything, from your experience, to keep in mind while planning large installations?

We are using 3.10 and have a 7 PB cluster. We decided against 16+3 as the rebuild time are bottlenecked by matrix operations which scale as the square of the number of data stripes. There are some savings because of larger data chunks but we ended up using 8+3 and heal times are about half compared to 16+3. -Alastair On 30 June 2017 at 02:22, Serkan ?oban <cobanserkan at gmail.com>

I am using 3.7.11 and only problem is slow rebuild time when a disk fails. It takes 8 days to heal a 8TB disk.(This might be related with my EC configuration 16+4) 3.9+ versions has some

Did you test healing by increasing disperse.shd-max-threads? What is your heal times per brick now?

I'm trying to justify a GlusterFS storage system for my technology development group and I want to get some clarification on something that I can't seem to figure out architecture wise... My storage system will be rather large. Significant fraction of a petabyte and will require scaling in size for at least one decade. from what I understand GlusterFS achieves redundancy through

I'm surprised you're happy with a non-polymorphic llvm. Does Cayenne target llvm? Dependent types take polymorphism to new heights -- but

During Gluster Summit, we discussed gluster volumes as storage for VM images - feedback on the usecase and upcoming features that may benefit this usecase. Some of the points discussed * Need to ensure there are no issues when expanding a gluster volume when sharding is turned on. * Throttling feature for self-heal, rebalance process could be useful for this usecase * Erasure coded volumes with

Normally things max out at ~150-250. The trick is to use multiple files, create the lvm stack and use native LVM striping. We have found that 4-6 files seems to give

Hi, Is there any existing support/on going work for zeroing buffers in llvm infrastructure? (either in the form of intrinsics or IR code buffer erasure?) My basic "grep" did not show up any. Please let me know any info on this. I will be glad to hear out! -- Anitha

Yes. This position requires Python and SQL. Sorry for the confusion.

Hello, we are currently managing access permissions through classical user-group-others permissions on a multi-petabyte directory tree with partially very deep and broad directories. Projects are represented by directory trees and mapped through GIDs. Lately we had lots of "singular" permission request (one single user needs access to a single dataset but should not be able to

Hi Take a look at this link (under ?Optimal volumes?), for Erasure Coded volume optimal configuration http://docs.gluster.org/Administrator%20Guide/Setting%20Up%20Volumes/ On Sat, Sep 23, 2017 at 10:01 Gandalf Corvotempesta < gandalf.corvotempesta at gmail.com> wrote: > Is possible to create a dispersed volume 1+2 ?

Already read that. Seems that I have to use a multiple of 512, so 512*(3-2) is 512.

Has anyone done any experiments with regards to type strengthening or weakening in the context of LLVM? For example, the GWT compiler does type strengthening - that is, if you are calling a method on an interface or abstract type, and the compiler determines through live variable analysis what the concrete type is, then it goes ahead and re-writes the type information to be the stronger
