Unable to delete cell because of maestro view

Hello,

I created a schematic and a maestro test bench to simulate my schematic. After finishing my simulations and extracting my results, I deleted the cell (right-click -> delete)

The cell views are deleted but the cell remains, and I get the following messages:

*WARNING* Window 1 does not exist
*WARNING* ddDeleteObj: Failed to unlink $PWD/myLib/myCell/maestro/results/maestro/.nfs0000000000f7efb90000133d - Device or resource busy
*WARNING* ddDeleteObj: Failed to remove directory $PWD/myLib/myCell/maestro/results - Directory not empty
*WARNING* ddDeleteObj: Failed to remove directory $PWD/myLib/myCell/maestro - Directory not empty
*WARNING* ddGetOAObject: Couldn't find an OA cellview object for view 'maestro' in lib 'myLib', cell 'myCell'
*WARNING* ddDeleteObj: Failed to unlink $PWD/myLib/myCell/maestro/results/maestro/.nfs0000000000f7efb90000133d - Device or resource busy
*WARNING* ddDeleteObj: Failed to remove directory $PWD/myLib/myCell/maestro/results - Directory not empty
*WARNING* ddDeleteObj: Failed to remove directory $PWD/myLib/myCell/maestro - Directory not empty
*WARNING* ddDeleteObj: Failed to remove directory $PWD/myLib/myCell - Directory not empty

The problem is that I can no longer open a maestro cell view in that cell (but I can create one). I can't do "rm -r" to the directory either.

Any help would be highly appreciated.

Best regards,
Karam

Hi Karam,

These .nfs<whatever> files occur on nfs mounted filesystems when some process tries to delete a file while another process is still holding a filedescriptor for that file's inode. You might try
% lsof $PWD/myLib/myCell/maestro/results/maestro/.nfs0000000000f7efb90000133d
to find that process.

Hello Max,

So it happened again, virtuoso is locking it even though I closed the assembler view

Karam,

Four questions:

Which subversion of Virtuoso are you using? (we asked earlier, but you didn't say)

What is the contents of the .nfs file you have left in the view?

Were you creating this view with the mae SKILL functions? I'm wondering whether you have an open session that way as well as interactively

Does lsof indicate virtuoso as the owning process for the leftover files?

Regards,

Andrew
