[lustre-discuss] cp fails on RHEL9.5 cp: error copying No data available

[Äkäslompolo Simppa]

Hi!

I thought I'd give an early warning this time.

We have HPE lustre client B19 + this patch https://review.whamcloud.com/c/fs/lustre-release/+/57007 on RHEL9.5

We just found out that copying doesn't work with cp. Possibly due to it using: copy_file_range to do the copying.

If the file is read into local cache, the copy succeeds. Otherwise you get "cp: error copying No data available" 

Back to RHEL9.4 --- again!

Best regards,
