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. Is it possible Ceph cannot find the destination PG fast enough and returns ERESTARTSYS? Is there any way to fix this behavior or reduce it?
