[Gluster-users] [Possibile SPAM] Re: Problem with Gluster 3.12.4, VM and sharding

[Gluster-users] [Possibile SPAM] Re: Problem with Gluster 3.12.4, VM and sharding
Hi, after our IRC chat I've rebuilt a virtual machine with FUSE based virtual disk. Everything worked flawlessly. Now I'm sending you the output of the requested getfattr command on the disk image: # file: TestFUSE-vda.qcow2 trusted.afr.dirty=0x000000000000000000000000 trusted.gfid=0x40ffafbbe987445692bb31295fa40105 trusted.gfid2path.dc9dde61f0b77eab=0x31326533323631662d373839332d346262302d383738632d3966623765306232336263652f54657374465553452d7664612e71636f7732 trusted.glusterfs.shard.block-size=0x0000000004000000 trusted.glusterfs.shard.file-size=0x00000000c15300000000000000000000000000000060be900000000000000000 Hope this helps.
