Hi all,
I am test ceph 0.56.6 with CentOS 6.3
I have one server, use raid 6, and then divided into 2 partitions (2 OSD)
With CentOS 6.3 (kernel 2.6.32-358), OSDs on the same server frequently
error:
" ......... osd.x [WRN] slow request x seconds old
....................................................... "
I think due to syncfs error.
I use command: grep -r syncfs /usr/include
Nothing is out
With kernel 3.9.0 :
grep -r syncfs /usr/include
/usr/include/asm-generic/unistd.h:#define __NR_syncfs 267
/usr/include/asm-generic/unistd.h:__SYSCALL(__NR_syncfs, sys_syncfs)
/usr/include/asm/unistd_32.h:#define __NR_syncfs 344
/usr/include/asm/unistd_64.h:#define __NR_syncfs
306
/usr/include/asm/unistd_64.h:__SYSCALL(__NR_syncfs, sys_syncfs)
/usr/include/bits/syscall.h:#define SYS_syncfs __NR_syncfs
Thus, kernel suitable for deployment CEPH ?
I need to install glibc or not?
I was under the impression that the 6.3 kernel did include the syncfs
call but didn't export it via glibc or anything, but maybe I'm
mistaken. Dan did the detection work for this and might know?

I believe you are correct Greg. I was able to get bobtail to use syncfs
on CentOS 5 so long as it had a modern kernel.
