Hi, How can we enable debug.trace so that we can inspect the debug data on different xlator? I just set “debug.trace on” and “debug.log-file yes” seems not work now. And one more update for this issue, if we set performance.stat-prefetch to off, the issue will not be occurred. (our previous

Re: [Gluster-devel] Custom Transport layers

Another thought that just occurred to me: security. There's no broadcast/unicast equivalent of TLS, so you're not going to have that protection. Maybe it doesn't matter in some kinds of deployments, but in others it would matter very much. Also, a similarly-secure broadcast/multicast

Re: [Gluster-devel] Issue about the size of fstat is less than the really size of the syslog file

Hi, I suppose there seems a defect on mdc_writev_cbk and mdc_fstat Let’s assume in 2 timestamp which called write and fstat operation in application: T0: write (process a) T1: read (process b) with the data of T0 of process a. T2: fstat (process c) In my view, mdc_write is non-block
