[Moosefs-users] How to delete metadata of unavailable chunks?

[Samuel H. O. N. <sam...@ol...>]

Hi there,

I am using MooseFS since 1 year and I did not encounter many metadata
errors. MooseFS is a very stable solution and we want to improve our
architecture.

When the mfsmaster encounter a problem, we launch a new one with the
metadata but some files information are missing and files are marked as
"0 valid copies" in the MFS interface. I am used to deal with this error
by manually deleting the files which are missing (usually a few, 100
max). But since the last problem we encounter we have approximatly 1000
files missing (not too bad, we have 33 millions of files...).

My question is pretty simple, how to automatically delete these files?
Because "no valid copies" causes filesystem hang when we try to access
to these files.

Thanks for your answers.

Best regards.
Sam
