[Gluster-users] Missing files with unify 2.0.0rc1

Hi,

I'm trying to use unify to replace my NFS servers but i have some problems.
In my tests I also see about a quarter of the fiels that I see on NFS.
I also get the following errors on my glusterfsd.log:

I don't think I have any hardware problems as I can cat all the files
in my home directory without any problem.

I tried to reproduce the problem with a smaller setup without much
luck unfortunately.

Here is the client file:

volume tintoretto
  type protocol/client
  option transport-type tcp
  option remote-host tintoretto
  option remote-subvolume brick
end-volume

volume giotto
  type protocol/client
  option transport-type tcp
  option remote-host giotto
  option remote-subvolume brick
end-volume

volume michelangelo
  type protocol/client
  option transport-type tcp
  option remote-host michelangelo
  option remote-subvolume brick

volume donatello
  type protocol/client
  option transport-type tcp
  option remote-host donatello
  option remote-subvolume brick
end-volume

volume ns
  type protocol/client
  option transport-type tcp
  option remote-host tintoretto
  option remote-subvolume ns
end-volume

volume bricks
  type cluster/unify
  option namespace ns # this will not be storage child of unify.
  subvolumes tintoretto michelangelo giotto donatello
#  option self-heal foreground # foreground off # default is foreground
#  option self-heal background # foreground off # default is foreground
### ** Round Robin (RR) Scheduler **
  option scheduler rr
# A server is not used if it's free disk space drops below 15%.
  option scheduler.limits.min-free-disk 15% #%
end-volume

volume bricks-rs
  type features/filter
  option root-squashing enable
  subvolumes bricks
end-volume

volume iot
  type performance/io-threads
  subvolumes bricks-rs
  option thread-count 4
end-volume

volume wb
  type performance/write-behind
  subvolumes iot
  option flush-behind off    # default value is 'off'
  option window-size 2MB
  option aggregate-size 1MB # default value is 0
end-volume

### 'IO-Cache' translator is best used on client side when a filesystem
has file
# which are not modified frequently but read several times. For example, while
# compiling a kernel, *.h files are read while compiling every *.c
file, in these
# case, io-cache translator comes very handy, as it keeps the whole
file content in
# the cache, and serves from the cache.
# One can provide the priority of the cache too.

volume ioc
  type performance/io-cache
  subvolumes wb
  option page-size 1MB      # 128KB is default
  option cache-size 64MB    # 32MB is default
  option cache-timeout 5 # 1second is default
  option priority *.c:2,*.h:1 # default is *:0
end-volume


### 'Read-Ahead' translator is best utilized on client side, as it
prefetches
# the file contents when the first read() call is issued.
volume ra
  type performance/read-ahead
  subvolumes ioc
  option page-size 1MB         # default is 256KB
  option page-count 4          # default is 2
  option force-atime-update no # defalut is 'no'
end-volume

[Gluster-users] Missing files with unify 2.0.0rc1

Filipe,
  how did you populate data into your volumes? was it pre-exising data
or did you copy in all data into a freshly created empty volume?

This is generally true, but in this situation he is using unify (which
does not use xattrs on the backend) and most of the other cases, if
the xattr is missing, the appropriate self heal will atleast try to
set the most sensible xattr values when the file is first looked up.
