Re: [MooseFS-Users] Segfault on client

[Aleksander W. <ale...@mo...>]

Hi.
Basically segfault is pointing problem in libc-2.11.1.so.

I see that you are using old Ubuntu distribution as MooseFS - SAMBA bridge.
Please consider to update your MFS - SAMBA bridge OS and MooseFS cluster.

MooseFS team released MooseFS 3.0.86 version lately and Ubuntu released
16.04 OS version. Many improvements ware made in both products.

By the way.
Please consider to use XFS as file system for MosoeFS chunkservers.
XFS better handle delete operations and is faster than EXT4 in case of
90% hard disk usage.
