Hi list,
I am in the process of migrating an embedded project from
ext2 to nilfs2 and have a problem with nilfs_cleanerd. It
does not start on mount and I cannot start it manually.
The below sequence is reproduced on the build system,
a QEMU i586, with a similar kernel as the target
(also i586, AMD Geode LX):
# mkfs.nilfs2 /dev/sdb1
mkfs.nilfs2 (nilfs-utils 2.1.1)
Start writing file system initial data to the device
Blocksize:4096 Device:/dev/sdb1 Device Size:2146765824
File system initialization succeeded !!
# mount.nilfs2 /dev/sdb1 /mnt/cf
# echo $?
0
# mount | grep nilfs
/dev/sdb1 on /mnt/cf type nilfs2 (rw,gcpid=489)
# nilfs-clean -l
No cleaner found on /dev/sdb1.
# dmesg | tail
...
segctord starting. Construction interval = 5 seconds, CP frequency < 30 seconds
# tail /var/log/syslog
...
Mar 14 16:48:50 monit kernel: segctord starting. Construction interval = 5
seconds, CP frequency < 30 seconds
Mar 14 16:48:51 monit nilfs_cleanerd[489]: start
Mar 14 16:48:51 monit nilfs_cleanerd[489]: cannot open nilfs on /dev/sdb1:
Function not implemented
Mar 14 16:48:51 monit nilfs_cleanerd[489]: cannot create cleanerd on /dev/sdb1:
Function not implemented
Mar 14 16:48:51 monit nilfs_cleanerd[489]: shutdown
Trying to start it manually with nilfs_cleanerd /dev/sdb1
gives the same result.
Kernel is a lean vanilla 3.2.11, but I have tried most
3.2.x kernels.
To a novice, like me, the lengthy strace below seems to
suggest a socket error of some sort (sendto(-1218631408,...).
Are there any specific kernel CONFIGs needed to get it
going?
