similar to: ZFS near-synchronous replication...

Does ZFS support any type of remote mirroring? It seems at present my only two options to achieve this would be Sun Cluster or Availability Suite. I thought that this functionality was in the works, but I haven''t heard anything lately. Thanks!

The GVN algorithm used in LLVM currently (I'm rewriting it) is the basic hash based RPO algorithm. The new one i'm writing is based on http://dl.acm.org/citation.cfm?id=512536 (see https://github.com/dberlin/llvm-gvn-rewrite) LLVM has different algorithms for both scalar PRE and load PRE. They are basically variants of standard PRE algorithms transformed into SSA, but with some

Whats available for doing near-realtime master->slave file replication between two CentOS systems? Cronjobs running rsync won't cut it. Ideally, I'd like something that works like SLONY-I does for Postgres databases, where all file system block level transactions on the master get replicated to the 2nd system on a 'as fast as practical' basis (a second or two of lag

Thanks that clears things up. So if I want to mess around with how schedules are generated, looking at the MachineScheduler pass is the best place now? -Dilan On Mon, Jul 31, 2017 at 3:24 PM Matthias Braun <mbraun at apple.com> wrote: > > > On Jul 31, 2017, at 2:51 PM, Dilan Manatunga via llvm-dev < > llvm-dev at lists.llvm.org> wrote: > > > > Hi, > >

Fairly new to ZFS. I am looking to replicate data between two thumper boxes. Found quite a few articles about using zfs incremental snapshot send/receive. Just a cheeky question to see if anyone has anything working in a live environment and are happy to share the scripts, save me reinventing the wheel. thanks in advance. -- This message posted from opensolaris.org

I have a backup system using zfs send/receive (I know there are pros and cons to that, but it''s suitable for what I need). What I have now is a script which runs daily, do zfs send, compress and write it to a file, then transfer it with ftp to a remote host. It does full backup every 1st, and do incremental (with 1st as reference) after that. It works, but not quite resource-effective

All; I have a question about ZFS and how it protects data integrity in the context of a replication scenario. First, ZFS is designed such that all data on disk is in a consistent state. Likewise, all data in a ZFS snapshot on disk is in a consistent state. Further, ZFS, by virtue of its 256 bit checksums is capable of finding and repairing data corruption should it occur. In the case of a

Hello, I was wondering whether or not some behaviour that I am seeing is expected behaviour and that it has been designed like this, or not. A dominator relation is given by "if A dominates B", then all paths to B go through A. For example, take the CFG below (which is a directed graph (couldn’t make the arrow heads but ok.): A / \ B C \ / D | E We can construct

hello list, i have a problem regarding the synchronisity (clock source) when using multiple cards. e.g. when having connected one PRI port of our TE410P to the telco, i need to have the analog card like the TDM400P or a B410P synchronous to the clock of our telco provider. otherwise faxing on the analog cards does not work or i get cracking noise or even hangups on my BRI lines, due to bit slips.

Got my first round of IP500s in today. Anybody have any example sip.cfg files they'd like to share?

Hi,all! Have you ever use this command volume sync <HOSTNAME> [all|<VOLNAME>] to <http://dict.cn/synchronous> synchronous a volume ? I haven?t use it successfully. When I use it ,system remind me ?please delete the volume?, after I delete the volume, system remind me ?the volume doesn't exist!?. What?s the purpose of this command? Thank you!

Hi all, is it just me or has this list stopped working. I haven't received anything for a couple of days now. Cheers, James.

The big problem that I have with non-directio is that buffering delays program execution. When reading/writing files that are many times larger than RAM without directio, it is very apparent that system response drops through the floor- it can take several minutes for an ssh login to prompt for a password. This is true both for UFS and ZFS. Repeat the exercise with directio on UFS and there is no
