Please read and help .... Bug or feature in VMFS 6

Jump to solution

In the file .vh.sf you should find 1024 entries for "abcdef0"

[root@localhost:/vmfs/volumes/5d94db91-49223634-6ebf-000c294514fd] od -t x4 .vh.sf | grep -c "abcdef0"

1024

The vast majority should have abcdef01 while a small number can have abcdef02.

Do you see entries with abcdef03 or abcdef04 ?

I am trying to figure out if the entries abcdef03 and abcdef04 are the result of corruption or wether they are the result of a new unknown feature.

If  you see those entries - do you have problems with locked files ?

This is a valid type of lock - so not alarming in itself ....

Just in case someone reads this post ...

Please help me ....

at the moment I think that a lock with abcdef03 is an indication of a corrupt heartbeat.

I am not sure about abcdef04 ....

If I have more numbers I can create a patch to fix the problem ...

Thanks

New locktype abcdef04 confirmed.

Still not sure if it is a bug or a feature.

Please report if you see it - it would help to find out in which conditions it is used.

At the moment I dont know how to fix it with minimal invasive operations ...
