Re: How to clear split brain info

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hmmm, strange, I went through all my bricks with every time the same result: 

-bash: cd: /mnt/public/brick1/.glusterfs/31/38/3138d605-25ec-4aa9-9069-5db2e4202db4: No such file or directory

The directory /mnt/public/brick1/.glusterfs/31/38 does exist, and indeed there’s a symlink in there but not one with the referenced gfid. 

Any further suggestions? If I can get rid of the message it’s ok.

Thanks in advance.

Kind regards
Davy
