NAME¶

lsm_volume_raid_create_cap_get - Retrieves supported capability of lsm_volume_raid_create()

SYNOPSIS¶

int lsm_volume_raid_create_cap_get (lsm_connect *conn, lsm_system *system, uint32_t **supported_raid_types, uint32_t *supported_raid_type_count, uint32_t **supported_strip_sizes, uint32_t *supported_strip_size_count, lsm_flag flags);

ARGUMENTS¶

conn

Valid connection.

system

Pointer of lsm_system.

supported_raid_types

Output pointer of uint32_t array. Containing lsm_volume_raid_type values. Memory should be freed via free. Valid values are: LSM_VOLUME_RAID_TYPE_RAID0
Stripe. LSM_VOLUME_RAID_TYPE_RAID1
Two disks Mirror LSM_VOLUME_RAID_TYPE_RAID3
Byte-level striping with dedicated parity LSM_VOLUME_RAID_TYPE_RAID4
Block-level striping with dedicated parity LSM_VOLUME_RAID_TYPE_RAID5
Block-level striping with distributed parity LSM_VOLUME_RAID_TYPE_RAID6
Block-level striping with two distributed parities,
aka, RAID-DP LSM_VOLUME_RAID_TYPE_RAID10
Stripe of mirrors LSM_VOLUME_RAID_TYPE_RAID15
Parity of mirrors LSM_VOLUME_RAID_TYPE_RAID16
Dual parity of mirrors LSM_VOLUME_RAID_TYPE_RAID50
Stripe of parities LSM_VOLUME_RAID_TYPE_RAID60
Stripe of dual parities LSM_VOLUME_RAID_TYPE_RAID51
Mirror of parities LSM_VOLUME_RAID_TYPE_RAID61
Mirror of dual parities LSM_VOLUME_RAID_TYPE_JBOD
Just bunch of disks, no parity, no striping.

supported_raid_type_count

Output pointer of uint32_t. Indicate the item count of supported_raid_types array.

supported_strip_sizes

The pointer of uint32_t array. Containing all supported strip sizes. Memory should be freed via free.

supported_strip_size_count

The pointer of uint32_t. Indicate the item count of supported_strip_sizes array.

flags

Reserved for future use, must be LSM_CLIENT_FLAG_RSVD.

VERSION¶

1.2
