Hi,
when using the newest Debian (testing) kernel 3.16.7 and its aufs.ko
3.16-20140908 and the current aufs-utils origin/aufs3.14, the mounting
takes about 15 seconds for each AUFS-mount:
# mkdir -p /tmp/aufstest/ro /tmp/aufstest/rw /tmp/aufstest/dest
# time mount -t aufs -o br=/tmp/aufstest/rw=rw:/tmp/aufstest/ro=ro aufs
/tmp/aufstest/dest
real 0m14.929s
user 0m0.160s
sys 0m1.916s
strace shows, that this happens because many repeating (more than 45000)
sleeps:
...
ioctl(4, AGPIOC_ALLOCATE, 0) = -1 EOPNOTSUPP (Operation not supported)
nanosleep({0, 100000}, NULL) = 0
ioctl(4, AGPIOC_ALLOCATE, 0) = -1 EOPNOTSUPP (Operation not supported)
2174 nanosleep({0, 100000}, NULL) = 0
...
I have no idea, what this means.
This does not happen, when using Debian's aufs-tools which a version
number that seems outdated to me: 1:3.2+20130722-1.1
Should I remove the self-compiled aufs-utils and use Debians aufs-tools?
Best regards, Erik
