<font color="#000066"><font size="2"><font face="trebuchet ms,sans-serif">All:<br><br>Apologies but I am new to this list, and somewhat new to XFS.<br><br>I have a use case where I'd like to forward the use of XFS. This is for large (multi-GB, say anywhere from 5GB to 300GB) individual files, such as what you'd see under a database's data file / tablespace. <br>
<br>My database vendor (who, coincidentally markets their own filesystems and operating systems) says that there are certain problems under XFS with specific mention of corruption issues, if a single root or the metadata become corrupted, the entire filesystem is gone, and it has performance issues on a multi-threaded workload, caused by the single root filesystem for metadata becoming a bottleneck.<br>
<br>This feedback from the vendor is surely taken with a grain of salt as they have marketing motivations of their own product to consider. <br><br>Surely, something like corruption and bottlenecks under heavy load / multi-threaded use would be a bug that would be addressed, right? <br>
<br>And surely, something like a BTree structure, with a root node, journaled metadata, etc. would be inherent in other filesystem choices as well, right?<br><br>The vendor, in the end, did recommend ext4, but ext4 is not in my mainline Linux kernel as anything beyond "tech preview" at this point. <br>
<br>Thanks in advance for any/all feedback.<br><br>Angelo <br></font></font></font>
