epi.2by2
This is a really simple question, I'm sure,but I can't make EpiR work!
I keep getting the following:
> epi.2by2(47, 263483, 282, 935028, method="cohort.time", conf.level=0.95)
Error in epi.2by2(47, 263483, 282, 935028, method = "cohort.time",
conf.level = 0.95) :
unused argument(s) (935028)
and I really don't know why!. Any ideas very very welcome
thank

Slow performance of gluster volume
OK my understanding is that with preallocated disks the performance with
and without shard will be the same.
In any case, please attach the volume profile[1], so we can see what else
is slowing things down.

dbench strange results
Hi
I'm building new samba server (on Debian 6.0, software RAID10 2TB, Xeon
CPU). Generally everything is working fine, so I have decided to run
some stress tests. My choice was dbench. Old server is Debian 4.0 (samba
3.0.24, Athlon 3000+, one ATA 160GB disk). So run
dbench 16
on both old and new server
The results are strange
old serwer: about 300MB/sek (dbench 3.0)

btrfs balancing start - and stop?
Hi,
My company is testing btrfs (kernel 2.6.38) on a slave MySQL database
server with a 195Gb filesystem (of which about 123Gb is used). So far,
we''re quite impressed with the performance. Our database loads are high,
and if filesystem performance wasn''t good, MySQL replication wouldn''t
be able to keep up and the slave latency would begin to climb. This
though, is

Slow performance of gluster volume
Hi Krutika,
I already have a preallocated disk on VM.
Now I am checking performance with dd on the hypervisors which have the
gluster volume configured.
I tried also several values of shard-block-size and I keep getting the same
low values on write performance.
Enabling client-io-threads also did not have any affect.
The version of gluster I am using is glusterfs 3.8.12 built on May 11 2017
