Re: Inefficient Snapshot disk space usage?

Well, that explains the snapshot creation. Is there some way to disable them? I like the idea of having snapshots, but I want to control when they are made so that I can avoid this situation in the future. It looks like when I create a new device the checkbox is unchecked...does it enable the snapsh...

Re: Inefficient Snapshot disk space usage?

I guess I'm still a little bit confused... In those threads, where does it talk about reclaiming the extra disk space that is being eaten up? Am I missing it? Since my post, I have had a couple of developments. I had a network issue that caused one of the mpio links to go down. In the process of tro...

Inefficient Snapshot disk space usage?

Hello, I'm running StarWind 5.8 on Windows 2008 R2 and I've got some issues with Starwind unnecessarily chewing up disk space when it relates to snapshots... Basically what I've got is a StarWind server serving a single VMware host via a 1tb CDP device. My disk space usage according to VMware is a l...

Re: Grossly bloated deduplicated target

Okay, thanks. I'll create some other disk type and maybe give that a try again when that issue gets worked out. But for now, at least I have a plan.

Re: Grossly bloated deduplicated target

You absolutely should NOT use thin-provisioned disks with deduplication. Basically you make double work for everyone. Deduplication IS thin-provisioning by design. Layering extra layer of TP over it makes data more scattered, more random I/O => low performance. That's good to know now. :) I`m askin...

Re: Grossly bloated deduplicated target

I'm also finding that copying the data off and creating a new target is more difficult than it sounds in an free ESXi environment. Apparently transferring files (the actual vmware files themselves) off of ESXi using SCP or Veeam's FastSCP is very slow (10-20MB/s), I guess by VMware's design from wha...

Re: Grossly bloated deduplicated target

Thanks for the reply, Anatoly. Wow, if I'm understanding you correctly, that's kind of a big bug. :| Does this only apply to deduplicated disks? I don't remember this being an issue on other installs I have done where I have used some other type of starwind disk. Going by my graph, it only gradually...

Re: Grossly bloated deduplicated target

It looks like my growth is mostly going into the .spbitmap and .spdata files, with a very small amount of grown in the .spmetadata file. Since my original post, I'm down another 1.2GB, with about half of that space going into the .spbitmap and .spdata files. It also looks like the gradual consumptio...

Grossly bloated deduplicated target

This morning I came in and found that my monitoring system was giving me alarms on my SAN server getting close to running out of diskspace. I have Starwind 5.8 installed on Windows 2008 R2. My target is on a 1.22TB raid array by itself (there is nothing else on that volume). I've got about 62.5GB fr...

Re: Device mount time

Ahh okay, that makes sense. So it's basically doing a recovery when that happens. I got it.

Does the same thing happen during a graceful shutdown/reboot? I haven't tested this so I don't know, but I'm curious.

Device mount time

How long should a device take to mount after a Starwind server is rebooted? We have a small setup of 1 Starwind server and 1 VMware server and occassionally the power goes out at our office. I've noticed that when the power comes back on and both servers come back online, the automatic start for the...

Re: A (hopefully) quick question about disk block sizes

Thanks for your response Anatoly. Is using a GPT more to get over the disk size limitations of MBR? Or is there some performance benefit to this also? Sounds like I'm good on the RAID 10, if I'm reading that correctly. RAID5 or 6 are the bad ones. How about RAID50? And as far as stripe size, it soun...
