Is that the same case with zumastor? like if I have /dev/lvmv/guss mounted and I do 2009-07-10 11:47 zumastore define volume gussorig /dev/lvmv/guss /dev/lvmv/snaptarget --initialize 2009-07-10 11:48 is the original mount still valid?

I think i'm not quite understanding something right.. if I already have a online mounted logical volume, I can't apply zumastor to that volume. If I zumerize an offline volume I can no longer access that original 2009-07-12 15:34 volume directly 2009-07-12 15:34 right, you have to access it via the ddsnap device 2009-07-12 15:35 origin and/or snapshots 2009-07-12 15:36 this means lets say your trying to build a production system.. for every volume you ever plan to snapshot you have to run zumastor before and always access that volume through zumastor? 2009-07-12 15:36 true 2009-07-12 15:36 sorry about that 2009-07-12 15:36 gotcha 2009-07-12 15:36 yeah.. I'm building a nas device 2009-07-12 15:36 and... right now I'm cheeting in that I create a hidden volume (not shown to the user) with the extents size 1 2009-07-12 15:37 ddsnap for designed for nas, indeed 2009-07-12 15:37 and then plan on growing that if they turn on snapshots 2009-07-12 15:37 does that sound like a good idea? ;) 2009-07-12 15:37 one caveat for ddsnap with NAS: although it is considerably better than lvm snapshot, it still has a rather large penalty for write performance 2009-07-12 15:38 yeah.. awesome work btw.. I currently have a couple of our linux devs looking into zumastor to extend the 64 limit 2009-07-12 15:38 okay 2009-07-12 15:38 larger than the known lvm snapshot? 2009-07-12 15:38 (performance) 2009-07-12 15:38 overall performance vs certain expensive proprietary nas ends up being quite decent 2009-07-12 15:39 sure 2009-07-12 15:39 the plan is to use the versioned pointers work for tux3 to extend the 64 snapshot limit 2009-07-12 15:39 prototype code is available 2009-07-12 15:39 though i would not call it a trivial task to integrate it into ddsnap 2009-07-12 15:40 by the way, when you say "our linux devs", who is "us" ? 2009-07-12 15:41 okay.. I still need to support block level as well.. so for that cause tux3 doesn't quite work.. would work well for those volumes the controller directly nas's out 2009-07-12 15:41 well, and tux3 doesn't have snapshots yet 2009-07-12 15:41 k 2009-07-12 15:42 it's a year or two away from being usable for nas, and yes, snapshotted block device can do things that a filesystem cannot 2009-07-12 15:42 so there is more work planned on ddsnap, but the focus is on tux3 2009-07-12 15:42 it's a team of 3/4 developers.. paid through a company.. I have the company contributing back to the community through a couple fronts. 2009-07-12 15:43 going to compete with netapp? 2009-07-12 15:43 :) 2009-07-12 15:43 :) 2009-07-12 15:43 that's a big shoe to fill, but the smb market 2009-07-12 15:44 some of where apple left 2009-07-12 15:44 yes, apple seems to have abandoned it 2009-07-12 15:44 well, even bigcos are hurting about the high price of NAS 2009-07-12 15:45 but they are also very slow to change 2009-07-12 15:45 current strategy just the recession seems to be, just don't add storage 2009-07-12 15:45 yes.. definitely 2009-07-12 15:46 yeah... but there seems to be a good opening on the smaller front.. most smaller companies don't know how to set up a vialable storage solution.. it's way to complex for most 2009-07-12 15:48 I guess I wouldn't say complex.. just it has a barrier.. and mostly too $$$ 2009-07-12 15:48 true 2009-07-12 15:49 it's really intersting how this area has not really progressed in the past 20 years ;) hehe 2009-07-12 15:50 fascinating and inexplicable 2009-07-12 15:50 soo.. okay. if you zumerize a filesystem and never apply a snapshot, would you still incure a large performance penalty? 2009-07-12 15:50 no 2009-07-12 15:51 yeah.. you look at storage systems for VAX's and they were pretty decent! 2009-07-12 15:51 overhead of snapshotted volume with no snapshots set is minimal 2009-07-12 15:51 ooo great! 2009-07-12 15:59 I just saw your post about lazy bitmap update.. we'll probably give it a try :D 2009-07-12 16:01 lazy bitmap update? 2009-07-12 16:01 ah 2009-07-12 16:02 write optimization? 2009-07-12 16:04 yeah.. that'd be for write optimizations to the master? 2009-07-12 16:04 yes, good 2009-07-12 16:04 that optimization speeds things up significantly 2009-07-12 16:05 I would be happy to merge any work you do on it 2009-07-12 16:05 that patch reduces write overhead by roughly 20% 2009-07-12 16:06 ooo cool.. did that patch turn out to be pretty stable? or would it need some hardening? 2009-07-12 16:06 Loading settings for ircii-EPIC... 2009-07-12 16:06 ircII:#zumastor> 2009-07-12 16:06 oops 2009-07-12 16:06 pretty stable 2009-07-12 16:07 really just needed testing 2009-07-12 16:07 k 2009-07-12 16:08 the email says "probably doesn't work yet" 2009-07-12 16:08 yeah hehe 2009-07-12 16:08 that means, somebody has to test and make sure the snapshots have the right data in them 2009-07-12 16:08 e.g., by checksumming files 2009-07-12 16:08 right 2009-07-12 16:11 I think the 64 limit, and write optimzations, and on the fly resize of the origin will be the top of the list 2009-07-12 16:12 yes 2009-07-12 16:13 origin resize is pretty simple, maybe even already done 2009-07-12 16:13 I think the patch is already in 2009-07-12 16:13 oh, on the trunk? 2009-07-12 16:13 yes 2009-07-12 16:13 the tarball is a little ancient 2009-07-12 16:14 k.. that's awesome if that's in their tho..
