Re: [Gluster-users] Performance is falling rapidly when updating from v5.5 to v7.0

I did another test with inode_size on xfs bricks=1024Bytes, but it had also no effect. Here is the measurement: (All values in MiB/s) 64KiB1MiB 10MiB 0,16 2,52 76,58 Beside of that I was not able to set the xattr trusted.io-stats-dump. I am wondering myself why it is not

[Gluster-users] Add existing data to new glusterfs install

This is related to my previous post "Sudden,dramatic performance drops with Glusterfs" Is it possible to install glusterfs on an existing server and filesystem, and migrate all of that existing data into a glusterfs volume. The ultimate goal would be to create a single-bricked volume,

Hello Rafi, I tried to set the xattr via setfattr -n trusted.io-stats-dump -v '/tmp/iostat.log' /gluster/repositories/repo1/ but it had no effect. There is no such a xattr via getfattr and no logfile. The command setxattr is not available. What I am doing wrong? By the way, you mean to increase

[Gluster-users] how to downgrade GlusterFS from version 7 to 3.13?

Hello, Is there any way to downgrade a GlusterFS cluster? Given the performance issues that I have seen with GlusterFS 6 and 7 (reported elsewhere on this mailing-list), I am now considering downgrading back to GlusterFS 3.13. I have set up a test cluster, copied some files on it, and tried to
