CC our file system people Jeff to this loop. >From my view, I feel the file system recovery time usually depends on file >system journal size, not file system size. Hello Jeff, do you think XFS will take 5 ~ 10 mins during the mounting after a uncleanly switch. Thanks Gang >>> On 6/12/2019 at

It may be off topic - but for such large filesystems journal check IS a problem. You may look at for ex. ZFS, it doesn't have a need for any journal recovery or fsck on mount (but it may be slower on some performance use cases, please test everything before use).12.06.2019, 08:30, "Indivar Nair"

Thanks, Gang It is a very large file system - around 600TB. Could this be why it takes around 5 - 10mins to do journal recovery? What we do as a workaround is - - Disable the filesystem resource on startup - Manually mount it (wait for as long as it takes) - Then umount it - Enable filesystem

Hello ..., I have an Active-Passive cluster with two nodes hosting an XFS Filesystem over a CLVM Volume. If a failover happens, the volume is mounted on the other node without a recovery that usually happens to a volume that has not been cleanly unmounted. The FS journal is on the same volume.
