What types of storage drives can be used for the Qlik Replicate and Qlik Enterprise Manager data folder?
Using unsupported storage types can lead to issues such as:
- Cannot stop or kill defunct tasks, even if services are restarted and tasks are manually stopped
- Log files cannot be accessed
- SQLite general error. Code <5>, Message <database is locked>
Environment
Qlik recommends using a block device (physical, virtual or iSCSI-based) for the Qlik Replicate and Qlik Enterprise Manager data folder.
- Using NFS or SMB-based storage is not supported due to the associated latency which could greatly degrade the data transfer performance, as well as due to reduced reliability and compatibility issues.
- Using of UNC path is not supported, such as \\mymapdrive\qlik\data
- Qlik Replicate also does not support EFS due to its reliance on SQLite to store configuration information. See Qlik Replicate: Amazon Elastic File System (EFS) not supported for Linux Deployments.
