Hello, I'm having an issue with nginx writing to cephfs. Often I'm getting:
writev() "/home/ceph/temp/44/94/1/0000119444" failed (4: Interrupted system call) while reading upstream looking with strace, this happens: ... write(65, "e\314\366\36\302"..., 65536) = ? ERESTARTSYS (To be restarted) It happens after first 4MBs (exactly) are written, subsequent write gets ERESTARTSYS (sometimes, but more rarely, it fails after first 32 or 64MBs, etc are written). Apparently nginx doesn't expect this and doesn't handle it so it cancels writes and deletes this partial file. Looking at the code, I saw it doesn't handle ERESTARTSYS in any different way compared to other write errors. Shouldn't it try to write same data again for a couple of times before finally giving up and erroring out? Do you have any suggestions on how to resolve this? I'm using latest stable nginx.
