Re: [Gluster-devel] Bitrot: Time of signing depending on the file size???

Hello Kotresh,

Yes, the fd was still open for larger files. I could verify this with a 500MiB file and some smaller files. After a specific time only the fd for the 500MiB was up and the file still had no signature, for the smaller files there were no fds and they already had a signature. I don't know the reason for this. Maybe the client still keep th fd open? I opened a bug for this:

David

Interesting observation! But as discussed in the thread bitrot signing processes depends 2 min timeout (by default) after last fd closes. It doesn't have any co-relation with the size of the file.
Did you happen to verify that the fd was still open for large files for some reason?

Hello folks,

I did some observations concerning the bitrot daemon. It seems to be that the bitrot signer is signing files depending on file size. I copied files with different sizes into a volume and I was wonderung because the files get their signature not the same time (I keep the expiry time default with 120). Here are some examples:

300 KB file ~2-3 m
70 MB file ~ 40 m
115 MB file ~ 1 Sh
800 MB file ~ 4,5 h

What is the expected behaviour here?
Why does it take so long to sign a 800MB file?
What about 500GB or 1TB?
Is there a way to speed up the sign process?

My ambition is to understand this observation
