[Gluster-users] filling gluster cluster with large file doesn't crash the system?!

[Craig Carl]

Matt, 
Based on your Gluster servers configs that file is bigger than the available disk space, obviously that isn't right. 

Can you send us the output of `stat y.out` taken from the Gluster mount point and from the back end of the server Gluster created the file on? 

I'm also going to try and reproduce the problem here on 3.1 and 3.1.1qa5. 





Thanks, 
Craig

Matt - 
A couple of questions - 

What is your volume config? (`gluster volume info all`) 



gluster> volume info all 


Volume Name: gs-test 
Type: Distribute 
Status: Started 
Number of Bricks: 2 
Transport-type: tcp 
Bricks: 
Brick1: 172.16.1.76:/exp1 
Brick2: 172.16.2.117:/exp2 





What is the hardware config for each storage server? 



brick 1 = 141GB 
brick 2 = 143GB 




What command did you run to create the test data? 


#perl -e 'print rand while 1' > y.out & 





What process is still writing to the file? 



same one as above. 








Thanks, 
Craig

I should also note that on this non-production test rig the block size 
on both bricks is 1KB (1024) so the theoretical file size limit is 
16GB. so how then did i get a file of 200GB?
