We need to create xfs file-system on kafka disk

The special thing about kafka disk is the disk size

kafka disk have 20TB size in our case

I not sure about the following mkfs , but I need advice to understand if the following cli , is good enough to create xfs file system on huge disk ( kafka machine )

 mkfs.xfs -L kafka  /dev/$DISK -f      

kafka best practice

FileSystem Selection Kafka uses regular files on disk, and such it has no hard dependency on a specific file system. We recommend EXT4 or XFS. Recent improvements to the XFS file system have shown it to have the better performance characteristics for Kafka’s workload without any compromise in stability. Note: Do not use mounted shared drives and any network file systems. In our experience Kafka is known to have index failures on such file systems. Kafka uses MemoryMapped files to store the offset index which has known issues on a network file systems.

  • isn't syntax mkfs -t xfs ... ?

From the documentation you cited:

The XFS filesystem [...] does not require any change in the default settings, either at filesystem creation time or at mount.

Source: https://kafka.apache.org/documentation/#xfs

So it should just work. Also there is nothing special anymore about a 20TB device size.

Consider adding a partition table and then use /dev/sdb1 instead of /dev/sdb.
