Hello everyone,
I am trying to setup a server with the following configuration:
#
# Object Storage Brick 1
#
# low-level brick pointing to physical folder
volume posix1
type storage/posix
option directory /mnt/os1/export
end-volume
# put support for fcntl over brick
volume locks1
type features/posix-locks
subvolumes posix1
option mandatory on
end-volume
# put additional io threads for this brick
volume brick1
type performance/io-threads
option thread-count 4
option cache-size 32MB # this one is per thread
sub-volumes locks1
end-volume
#
# Object Storage Brick 2
#
# low-level brick pointing to physical folder
volume posix2
type storage/posix
option directory /mnt/os2/export
end-volume
# put support for fcntl over brick
volume locks2
type features/posix-locks
subvolumes posix2
option mandatory on
end-volume
# put additional io threads for this brick
volume brick2
type performance/io-threads
option thread-count 4
option cache-size 32MB
sub-volumes locks2
end-volume
#
# Metadata Storage
#
volume brick-ns
type storage/posix
option directory /mnt/ms
end-volume
#
# Volume to export
#
volume server
type protocol/server
subvolumes brick1 brick2 brick-ns
option transport-type tcp/server
option auth.ip.brick1.allow *
option auth.ip.brick2.allow *
option auth.ip.brick-ns.allow *
end-volume
i.e. as recommended in best practices and tuning guides, I put locks
translator over posix brick and after that io-thread translator over
lock brick.
if I try to start the server, it gives me following errors:
Starting glusterfs server: glusterfsd.

the server starts fine If I remove io-thread bricks at all and use
'locks bricks' as an export volumes.
Does it mean, that glustet is not able to put several translators in
the row in server configuration?
