Re: [Gluster-users] Slow performance on samba with small files

Hi, There is a number of tweaks/hacks to make it better, but IMHO overall performance with small files is still unacceptable for such folders with thousands of entries. If your shares are not too large to be placed on single filesystem and you still want to use Gluster - it is possible to run

Re: [Gluster-users] Vm migration between diff clusters

Hello, For offline migration you can use storage domain of type Export, shared between clusters. For online storage migration the source and destination storage have to be present in current cluster. Regarding the different glusterfs versions - it must not be a problem because oVirt uses vm im

Re: [Gluster-users] How to properly set ACLs in GlusterFS?

Hi, According to man page for setfacl: For uid and gid you can specify either a name or a number. But actually the information will be stored in xattrs in the form of numbers, afaik. One way to solve your problem is the consistent name/id mapping, which can be achieved by using directory serve

Re: [Gluster-users] dealing with gluster outages due to disk timeouts

Hi, I always though that hardware RAID is a requirement for SDS as it hides all dirty work with raw disks from software which just cannot deal with all kinds of hardware faults. If disk starts to experiencing long delays, then after about 7 seconds RAID controller marks this disk as failed (thi

Re: [Gluster-users] auth.allow doesn't seem to work

Hi, It looks like for NFS you have to change nfs.rpc-auth-allow, not auth.allow (which is for access by API). Docs for nfs.rpc-auth-allow states that "By default, all clients are disallowed", but in fact the option has "all" as default value. Regarding auth.allow and information disclosure usin

Re: [Gluster-users] write performance with NIC bonding

Hi, It is because your switch is not performing round-robin distribution while sending data to server (probably it can't). Usually it is enough to configure ip-port LACP hashing to evenly distribute traffic by all ports in aggregation. But any single tcp connections will still be using only one

[Gluster-users] Self healing does not see files to heal

Hello, While testing healing after bitrot error it was found that self healing cannot heal files which were manually deleted from brick. Gluster 3.8.1: - Create volume, mount it locally and copy test file to it [root@srv01 ~]# gluster volume create test01 replica 2 srv01:/R1/test01 srv02:/R1/t

Re: [Gluster-users] Bit rot disabled as default

Hello. May be because of current implementation of rotten bits detection - one hash for whole file. Imagine 40 GB VM image - few parts of the image are modified continuously (VM log files and application data are constantly changing). Those writes making checksum invalid and BitD has to recalcu
