Hi,
I' m using AFR to keep aligned a file system on two servers.
This file system contain oracle data.
Oracle works properly on the file system managed by AFR either on the server
A or server B.
But if I switch off server A while oracle is runnig and I launch oracle on
the second server all works fine.
When server A comes up again and i stop oracle on the server B and I try to
run oracle on the server A oracle doesn't work properly because there is
some file locked. ( After this operation oracle doesn't work on the server A
but works on the server B )
The only way to exit from this situation is to reboot server B, (the server
where oracle works properly).
Is there a way to force an unlock file or a way to avoid this behaviour?
Moreover when I switch off a server, the file system on the other server is
not available( the command ls remains blocked) for 25 seconds.
How can I do to have available the file system in a short time?
I'm using a 2.0.3 release and fuse 2.7.4.
I have two servers configured as follow:
client vol:
volume CRS
type protocol/client
option transport-type tcp/client
option remote-host 127.0.0.1
option remote-subvolume disk
end-volume
volume writeback-disk
type performance/write-behind
option block-size 131072 # unit in bytes
subvolumes CRS
end-volume
volume readahead-disk
type performance/read-ahead
option page-size 65536 # unit in bytes
option page-count 16 # cache per file = (page-count x page-size)
subvolumes writeback-disk
end-volume
server vol
volume local-disk-ds
type storage/posix
option directory /var/glusterfs/shared
end-volume
volume TSU-1.localdomain-disk
type features/locks
subvolumes local-disk-ds
end-volume
volume remote.localdomain-disk
type protocol/client
option transport-type tcp/client
option remote-host 192.168.1.74
option remote-subvolume TSU-2.localdomain-disk
option transport-timeout 5
end-volume
volume disk-afr
type cluster/afr
subvolumes remote.localdomain-disk TSU-1.localdomain-disk
option favorite-child TSU-1.localdomain-disk
end-volume
volume disk-unify
type cluster/distribute
subvolumes disk-afr
end-volume
volume disk
type performance/io-threads
option thread-count 2
subvolumes disk-unify
end-volume
volume server
type protocol/server
option transport-type tcp/server
subvolumes disk
option auth.addr.TSU-1.localdomain- disk.allow *
option auth.addr.local-disk-ds.allow *
option auth.addr.disk.allow *
end-volume
Thanks Maurizio
