Seems caused by the parse read ?
You mean sparse read? Those patches aren't in the wip-fscrypt branch
yet, so I wouldn't think them a factor here. What commit was at the top
of your branch?
If you're testing the latest sparse read patches on top of wip-fscrypt,
then those only work with msgr2 so far. Using msgr1 with it is likely to
have problems.
Okay, it seems another patch series. But I am not sure, this is the
latest commits in the wip-fscrypt branch I hit the issue:
ce03ef535e7b SQUASH: OSD
5020f1a5464b ceph: convert to sparse reads
8614b45d3758 libceph: add sparse read support to OSD client
a11c3b2673aa libceph: add sparse read support to msgr2 crc state machine
a020a702a220 (origin/testing) ceph: allow `ceph.dir.rctime' xattr to be
updatable
I just switched back to the branch I pulled days ago, it works well:
Yeah, I am using the '--msgr1'. Maybe this is a problem. I will try
'--msgr2' later.
