The thin_provisioned != dev_thin_provisioned condition isn't the best way for marking manually set thin_provisioned attribute. ----------------------------------- | thin_prov | dev_thin_prov | key | ---------------------------------- | 0, 1 | 0 | No | ----------------------------------- | 1 | 1 | No | ----------------------------------- | 0 | 1 | Yes | ----------------------------------- The thin_prov=1, dev_thin_prov=0 case leads to thin_prov will be set to 0 due to internal checking. So, it's possible to see the value of the thin_provisioned attribute via scstadmin only in the one case (3 row). It's especially unclear for the fileio devices, because they support thin provisioning only when the corresponding attribute is manually set. Thus, to clarify the using of the thin_provisioned attribute always display it when manually set.
Overview
This is the source code repository of the SCST project. SCST is a collection of Linux kernel drivers that implement SCSI target functionality. The SCST project includes:
- The SCST core in the scst/ subdirectory.
- A tool for loading, saving and modifying the SCST configuration in directory scstadmin/.
- Several SCSI target drivers in the directories iscsi-scst/, qla2x00t/, srpt/, scst_local/ and fcst/.
- User space programs in the usr/ subdirectory, e.g. fileio_tgt.
- Various documentation in the doc/ subdirectory.
Instructions for building and installing SCST are available in the INSTALL.md file.
QLogic target driver
Two QLogic target drivers are included in the SCST project.
The default driver is located in qla2x00t-32gbit directory and it supports up to 32 Gb/s FC. It is the newer one.
May anyone wish to switch back to the older driver that only supported up to
16 Gb/s adapters, it is located in qla2x00t directory. To make use of the
older driver build scst with environment variable QLA_32GBIT=no set.
