[Gluster-users] Information about Option min-free-disk

[Dragon]

Hello,

i have a question about the Volume Option min-free-disk. Actually i set it to 1%. I understand this, that 1% auf the total Space e.g. 100GB out of 10TB will reserved for files which is copied in a distributed cluster. if the file is bigger, it will copied to the next node. i think 100GB is a lot space and  i didnt find out how to set it e.g to 0,5% or 10GB. is this possible and what would happend if i set it to zero, will i lost data?

 

Explain please

Re: [Gluster-users] GlusterFS Install Link ubuntu 12.04

[Brian]

THe Ubuntu Server package already has the client bundled in it (like a 
one-stop shop).


You will need to install the client package on each server that wishes 
to access the gluster servers.


So: the servers only need the server package. and the clients only need 
the client package.

Hi Brian,

Thank you. I found that package helpful and it worked :)

I have to install the package on Server and Client both (The one you 
provided right?).


I have just installed on one separate Gluster node, is that fine?

I already have Openstak and in that Storage node so should I install 
GLuster server package in that?


Thank you for your help in advance.

[Gluster-users] Samba vfs_glusterfs Quota Support?

[David Gibbons]

Hi All,

I'm setting up a gluster cluster that will be accessed via smb. I was
hoping that the quotas. I've configured a quota on the path itself:

# gluster volume quota gfsv0 list
path  limit_set  size
--
/shares/testsharedave   10GB8.0KB

And I've configured the share in samba (and can access it fine):
# cat /etc/samba/smb.conf
[testsharedave]
vfs objects = glusterfs
glusterfs:volfile_server = localhost
glusterfs:volume = gfsv0
path = /shares/testsharedave
valid users = dave
guest ok = no
writeable = yes

But windows does not reflect the quota and instead shows the full size of
the gluster volume.

I've reviewed the code in
https://forge.gluster.org/samba-glusterfs/samba-glusterfs-vfs/blobs/master/src/vfs_glusterfs.c
--
which does not appear to support passing gluster quotas to samba. So I
don't think my installation is broken, it seems like maybe this just isn't
supported.

Can anyone speak to whether or not quotas are going to be implemented in
vfs_glusterfs for samba? Or if I'm just crazy and doing this wrong ;)? I'm
definitely willing to help with the code but don't have much experience
with either samba modules or the gluster API.

Cheers,
Dave

Re: [Gluster-users] [Gluster-devel] GlusterFS 3.3.1 client crash (signal received: 6)

[Song]

Pranith,

Thanks for your detail answer. 

Our workload includes CREATE/WRITE/READ/STAT/ACCESS, as well as chmod(filepath, 
0). While I don't know which kind of workload lead to the crash.
We have analyzed the related code such as dict, lookup of cluster/afr, lookup 
of protocol/client and have nothing useful information to help locate the 
issues.

Song.

Song,
 The information printed in that function gf_print_trace has been useful in 
the sense that we know it happens when there is a double 'memput' of one of the 
data structures as part of 'lookup'. The problem is this issue seems to be 
happening only in some peculiar case, which unfortunately you are hitting every 
day on 1-2 clients. That is why I was trying to figure out what the workload is.

Let me tell you what I mean by 'workload' is.
For example:
For websites which do some kind of image manipulation. They generally CREATE 
temporary information and do some transformations i.e. READS/WRITES and then 
RENAME them to the actual files.
So here the work load is CREATE/READ/WRITE/RENAME intensive.

To give you one more example:
VM image hosting(At least with the KVM images that I test generally), On each 
VM image it pretty much does WRITES, READs, STATs so it is WRITEs/STATs/READs 
intensive.

I would really like to know what kind of workload happens on your setup to 
figure out what is that peculiar thing that may lead to this crash.

Pranith.

Re: [Gluster-users] New to GlusterFS

[Hoggins!]

Hey guys,

By the way, when I issue service glusterd stop and service glusterfsd
stop, there are still gluster* processes running on the machine, even
after a minute.
Is that a normal behavior, should I kill them directly, should I just
wait for them to die peacefully, or is it safe to shutdown the machine
at this moment ?

Thanks !
