Hi Michael,
I'm trying to reproduce the problem from sources (today's instead of
yesterday's but there is no difference that could explain the behaviour you
have):
cd src
rm -fr /tmp/dev /tmp/out ; mkdir -p /tmp/dev ; CEPH_DIR=/tmp LC_ALL=C
MON=1 OSD=6 bash -x ./vstart.sh -d -n -X -l mon osd
ceph osd erasure-code-profile set profile33 ruleset-failure-domain=osd k=3
m=3
ceph osd crush rule create-erasure ecruleset33 profile33
ceph osd pool create testec-33 20 20 erasure profile33 ecruleset33
./rados --pool testec-33 put SOMETHING /etc/group
but it succeeds. Could you please script a minimal set of commands I could
run to repeat the problem you're seeing ?
The file that I put into the pool was 15MB in size and the error occurred
after the first 4MB chunk. That might be the difference.
I will try to come up with a list of commands in case that doesn't trigger it
for you.
Here is a concise version of what I am deploying with (limited to 6 OSDs
in this example).
ceph-deploy new c1 c2 c3
pdsh -wc[1-3] yum -y install ceph
ceph-deploy mon create c1 c2 c3
sleep 30
cd /etc/ceph
ceph-deploy gatherkeys c1 c2 c3
machines=(c1 c2 c3)
for machine in ${machines[@]}; do
for n in {1..2}; do
ssh root@$machine 'rm -rf /data$n/osd$n && mkdir -p
/data$n/osd$n'
ssh root@$machine 'rm -rf /journals/journal-osd$n'
ceph-deploy osd prepare
$machine:/data$n/osd$n:/journals/journal-osd$n
ceph-deploy osd activate
$machine:/data$n/osd$n:/journals/journal-osd$n
done
done
# Wait for OSDs to settle
sleep 60
ceph osd erasure-code-profile set profile33 ruleset-failure-domain=osd k=3 m=3
ceph osd crush rule create-erasure ecruleset33 profile33
ceph osd pool create ectest-33 20 20 erasure profile33 ecruleset33
root@c1:~/ceph# rados -p ectest-33 put xyz sampledata
error putting ectest-33/xyz: Operation not supported
root@c1:~/ceph# du -h sampledata
15M sampledata
