Frederick, thanks for the patch list! It is nice to know the patch set(s) which is/are actually running in production. We are at zfs/spl 0.6.4.1 in production for the last six months with 2.5.3 last GA release (Sept'14).
Is tag 2.5.3.90 considered stable? I was cautious to use 2.5.3.90 as there can be critical patches before final release. There are not many differences between Intel's 2.5.3.90 and 2.5.3-llnl, if we disregard ldiskfs patches which we do not use. Until there are 'collateral' changes in the patch which are not reflected in commit message. We did try 2.5.3-llnl build, it was working fine with 2.5.3 clients (or 1.8.9 only). There were client crashes when we mounted both old 1.8.9 lustre and new lustre 2.5.3 on the same 1.8.9 client. We need that for transitional period as worker nodes need to access both 2.5 and 1.8 systems during migration. Last Intel's 2.5.3 GA release does not have this issue (+one stability patch). We moved most of the data to the new system and reconfigured most oss/ost to new 2.5.3 lustre. No "in-place" conversions. Thus the issue of compatibility with 1.8.9 client will be not relevant when we complete migration and upgrade clients. What client version shall we use with 2.5.3 servers? 2.5.3 is obvious. Reportedly 2.6 client has performance improvements. I build 2.7.0 client and rebalanced several TB with crc checks, seems OK. Is 2.7.0 stable? Shall we look on 2.8.0 client or it is too early? Alex.
