still can't make the qdisk working - after 5-10 seconds of qdiskd start
it locks awaiting some communication:
some more debugging of this issue:
the strace of qdiskd when getting locked:
lseek(6, 65536, SEEK_SET) = 65536
read(6, "\36\273\336\0`\224\213P\2265\v\3P\0\0\0\0\0\0\0\0\0\0\0"...,
512) = 512
select(4, [3], NULL, NULL, {0, 0}) = 0 (Timeout)
writev(3, [{"NAMC\3\0\0\20\30\0\0\0\267\0\0\200\0\0\0\0", 20},
{"\1\0\0\0", 4}], 2) = 24

what can be wrong?

hi,
I am running cluster 2.03.08.
after adding qdisk feature to twonode cluster, it somehow locks entire
cluster. without qdisk it runs ok.
