-MOUNT-F-MBRTOOSMALL,

I know there is another thread with the same name for the same problem, I need more information on this.

Both the disks are identical. Im not sure why this error is popping up.

This is on my personal alpha

Re: -MOUNT-F-MBRTOOSMALL,

Hi Joewee

DKA0 and DKA100 are not initialized the same way.
DKA100: Maximum files allowed 16711679
DKA0: Maximum files allowed 492946

Try to initialize DKA100 the same way as DKA0 is.

INIT(/nohigh) /LIMIT/OWNER=SYSTEM/SIZE=exactly-same-size-in-blocks-as-dka0 DKA100

Then try to add DKA100 into the shadow-set DSA4:

If there is no reason to use highwater marking I would recommand to disable higwater marking on DSA4, with SET VOLUME/NOHIGH DSA4.

Regards

Re: -MOUNT-F-MBRTOOSMALL,

Joewee,

could you please repeat the SHOW DEV/FULL commands after setting $ SET PROC/UNIT=BLOCKS ?

Interestingly, the other ITRC article also seems to have happened on an Alpha emulator (PersonalAlpha ?).

Volker.

Re: -MOUNT-F-MBRTOOSMALL,

Hi Geni,

I can do that.

I will give this option a try and I will let you know the out come.

Re: -MOUNT-F-MBRTOOSMALL,

Joewee,

the total no. of blocks and logical volume size are identical for both drives (8380080 blocks). But - for whatever reason - the Expansion size limit is different.

I'd suggest that you just do a plain INIT $4$DKA100: SCRATCH and try again. The device will be overwritten by the shadowcopy anyway.

Re: -MOUNT-F-MBRTOOSMALL,

Joewee,

what about $ INIT/LIMIT $4$DKA100: SCRATCH

If you look at the size of the .vdisk container files on your host operating system (Windows), what sizes are shown for the 2 .vdisk files ?

Re: -MOUNT-F-MBRTOOSMALL,

Volker,

On windows.

DKA100 - 3.99 GB (4,290,600,960 bytes)
DKA0 - 3.99 GB (4,290,600,960 bytes)

One more thing is, I have created the container file for DKA0 with the FreeAXP emulator, and the container file for DKA100 with Personal Alpha. I'm going to create another container file with FreeAXP and check. Very slimmest of chances are there still im gonna give a try.

Output:

Re: -MOUNT-F-MBRTOOSMALL,

Joewee,

and does the same error also happen when running under FreeAXP instead of PersonalAlpha ?
