Re: [Moosefs-users] Unavailable Chunks

[Stéphane B. <ste...@ga...>]

Thanks for the answer,

But it happens really often. Maybe every 2 or 3 loops. Maybe it is some 
settings wrong ? We have 2 chunkserver ... that means that both of them 
was unavailable. I changed the timeout settings a little.

Here is my settings.


Chunkservers:

MASTER_TIMEOUT = 2
HDD_TEST_FREQ = 10

This is the only 2 settings I changed

Masters:

CHUNKS_LOOP_TIME = 60
CHUNKS_DEL_LIMIT = 5000
CHUNKS_WRITE_REP_LIMIT = 5
CHUNKS_READ_REP_LIMIT = 10

This the only settings I changed the remaining should be Default


More explanation about the setup...

We have 2 master running Keepalived (same as carp)
the chunk servers are on the same servers as the master
the machines are Dual quad core Xeons with 8G of Ram
and 15k rpm disks in raid 5
