Hi everyone,
I was using FSAL_RGW to export nfsv3, and trying to copy files from
ceph-fuse mountpoint to the nfs mountpoint, file size is 1.5mb, but some
files write failed with "input/output error" returning.
After simply debug, I found that the error is because the write is
unordered, the file size is 1.5mb, so it need two write rpc, sometimes the
second rpc will processed first, then the librgw will return EIO fail. But
here's the strange thing, when I copy files from local fs dir, the problem
never appearance.
And the receiving order is always right, but processing order is not.
But why this never appearance when copy from local fs ? And Is there any
suggestion to fix? Really appreciate your help.
Thanks
ganesha version: i tried two version:2.6.2 and 2.8.1
ceph version: 12.2.5 luminous
And here is log of a failed writing:
