Some operations, like backup/restore and data loading, require you to either read or
write large files. You can mount a NAS (network attached storage) file system for these
This procedure shows you how to mount a NAS file system for storing or accessing
large files. The file system will be mounted at the same location on each node in the
cluster automatically. When any node is restarted, the file system will be mounted again
automatically, if it can be found.
When supplying a directory for writing or reading a
backup, you can specify the mountpoint as the directory to use. Likewise, you can
stage data there for loading.
Note that backups are written by the Linux user
"admin". If that user does not have permission to write to the NAS file system, you
could write the backups to disk (for example /export/sdc1, /export/sdd1,
/export/sde1, or /export/sdf1) and then set up a cron job that executes as root user
and copies the backup to the NAS device every night, then deletes it from the
Do not send the periodic backups or stage files on /export/sdb1
since it is a name node. It is used internally by Hadoop Distributed File System
(HDFS) and if this drive fills up, it can cause serious problems. Do not allow
backups or data files to accumulate on ThoughtSpot. If disk space becomes limited, the system will not function
