What do you mean under "crash"? Did you see Windows system message box with "This application bla-bla-bla and would be closed" or... What actually happened? According to the log (truncated one, BTW) the write failed b/s the underlying disk is full. I can bet you've created "sparse" a.k.a "unallocated" image file and it just grow up till the "hosting" disk limit. But to be 100% sure we need 1) complete and not truncated log 2) xml configuration file 3) some more detailed description from you what you did. "Is there a good reason for this crash" is *NOT* a description

Please provide us with missing data and we'd be happy to assist you.

Thanks!

Hi,
The error message seems that the disk partition has no free space to store IBVolume journals.

The matter is the AUTO_RESTORE_SNAPSHOT mode (3) use temporary journal files for each volume to storee the data that user writes to the disk inside the session.
On the session's close the journals are discarded and the space is returned to the free pool.

You need to store the log files for your IBVolumes to a disk volume that has enough free space for all the users.
For example, if your master volume is 10GB, the maximum disk usage for 50 users could reach 10*50+10+5= 515GB (if each user use 100% of his volume space for temporary data)

I hope this helps.

Damir, some more ideas:

2/25 22:43:28 c74 IBV: *ERROR* IBVolume_CreateInternal: 'J:\Journals\ibv48_00000001.ibvm': MapViewOfFile (err: 8 ).
2/25 22:43:28 c74 IBV: *ERROR* SscPort_Create: Create('My Computer\J\IBV\ibv48.ibv') error (0xc0000001)!
2/25 22:43:28 c74 SCSI: Failed to create 'IBV48' device.

1) Your master image is about 300 GB in size.
So each child IBVolume demands about 39MB of disk space for its 'map' file and each write to the volume consumes 64KB of journal space (the extent size is 128 sectors per extent for the disk size)

2) The bad news is each map file must be mapped to the memory of the StarWindService process so it needs 39MB*50 = 1950MB of memory for map files while a Win32 process is limited by 2GB of address space. So in the case all the available address space has been used.

3) To work around the address space limitation it's possible:
- Use large extent size for IBVolumes (256 is the maximum value). This will help to solve the address space problem as a map file size will be about 19.5MB in the case. But keep in mind that this will lead to bigger temporary journal files for sessions.
- Use a master image of shorter size, so the map files will be shorter too.

Here are some details on tuning of IBVolumes:
- Each IBVolume consists of 'extents' of constant size.
- From 1 to 256 sectors per extents is supported now.
- Each extent record use 8 bytes of the map file.
- The total size of all map files for your IBVolumes is limited by the process address space (2GB for Win32). In fact it's about 1.7GB.

So before creating your IBVolumes calculate total address space limit and use proper extent sizes.

I have another question now to you. How did it happen your logs are dated 25th of February? Are you using expired version of StarWind with just rolling back time to prevent it from not working? Would you please comment this. Thanks!

Hello!

Yes I would! As you can see, I am slow to respond. I have very little time to dedicate to this project, and considering it times out so quickly (15 days), I usually do a batch of testing, and then leave it for a long while until I can focus on it again. In this case, that was 4 months! I´ve been contenplating buying a version of starwind with unlimited connections, but I am fearful of doing so, because I am plagued by unexplained crashes. (This one I may understand, but I can add to the fact that even if StarWind is setup for 50 users, which would be a typical scenario for me, if I started using it in my envirioment, all the tests have had a max of 4 users simultaniously. Do you still think RAM is a problem, ie, the maximum allocetable process memory size? )

I have also tried emailing you about another matter, but I have not been able to, because your email server doesen´t like my email server, it returns the mail, telling me that it was sent from a unreliable IP adress)

And I have ONE more question

If I have a "set" of files on a disk, and I want to put them into a empty Image, how would I go about doing this from the command line, or other way, that is scriptable, so I dont need to manually mount the volume as a Image, copy things into it, then dismount it again, then remount it as a IBV volume.

Is there a *creative* way of doing this ? So one could stop the starwindservice, create a reference Image file, then start the starwindservice again.

It's very difficult to work with such a big "gaps" between request-response communications.

It's no problem to write down a request and get custom long-trial period. Also it's not a problem to create a free @gmail.com account to write to us from. Or ask in forum so we could authorize your mail server. Etc etc etc

As I said in the previous posting, there is a limitation for the maximum number of IBVolume targets in StarWind for Win32.
45 IBVolumes seems to be the limit.

This issue should not take place in StarWind for Win64 (native AMD64 build), that is available on request.

And I have ONE more question :P If I have a "set" of files on a disk, and I want to put them into a empty Image, how would I go about doing this from the command line, or other way, that is scriptable, so I dont need to manually mount the volume as a Image, copy things into it, then dismount it again, then remount it as a IBV volume.

No, there is no way to update your ImageFile target except through the iSCSI interface.

Thankyou for your answers.

I will think them over, and come back to you.

One quick question to Valery, how do I set extent size ? How much will
the journaling space requirements go up ?

Thankyou kindly,
Damir

Damir,

The more extent size, the less size of the map file, the more IBVolumes may be exported simultaneously.
When you create an IBVolume, it's possible to specify the extent size in the 'Specify sectors number' field.

If the user changes a single disk sector, the whole extent including the sector is written to the journal file.
The maximum journal size is equal to the IBVolume's size. This could happen if the user overwrites each extent inside the session.
