sys_attrs_cms(5)
NAME
sys_attrs_cms - cms subsystem attributes
DESCRIPTION
This reference page lists and describes attributes for the cluster mount
service (cms) kernel subsystem. Refer to the sys_attrs(5) reference page
for an introduction to the topic of kernel subsystem attributes.
cmsdbg_flags
Specifies which code sections are to be debugged and how the debug
messages are output.
Do not modify the default setting for this attribute unless instructed
to do so by Compaq Computer Corporation support personnel or by patch
kit documentation.
Supported operations: Query; Configure at boot time; Reconfigure at run
time
Default value: 0
Minimum value: 0
Maximum value: 18446744073709551615
cfs_advfs_mount_limit
Clusterwide limit on the number of AdvFS filesystems that can be
mounted in the cluster. You must ensure that this attribute has the
same value on all cluster members.
As members leave the cluster, the number of filesystems capable of
being simultaneously mounted in the cluster will decrease, thus
potentially causing the inability of a filesystem to failover. As a
result, if you do modify the cfs_advfs_mount_limit value, it should
reflect the number of members required for the cluster to have quorum.
For example, if there are two members are required for the cluster to
have quorum, then the value of this attribute should not exceed 8192
(2*4096). This value may additionally be limited by the memory
resources on a given cluster member, so that often a lower value may be
required for failover to be possible.
Supported operations: Query; Configure at boot time; Reconfigure at run
time
Default value: 4096
Minimum value: 0
Maximum value: number-of-members-required-for-quorum*4092
cfs_cdfs_mount_limit
Clusterwide limit on the number of CDFS filesystems that can be mounted
in the cluster. You must ensure that this attribute has the same value
on all cluster members.
As members leave the cluster, the number of filesystems capable of
being simultaneously mounted in the cluster will decrease, thus
potentially causing the inability of a filesystem to failover. As a
result, if you do modify the cfs_cdfs_mount_limit value, it should
reflect the number of members required for the cluster to have quorum.
For example, if there are two members are required for the cluster to
have quorum, then the value of this attribute should not exceed 1024
(2*512). This value may additionally be limited by the memory
resources on a given cluster member, so that often a lower value may be
required for failover to be possible.
Supported operations: Query; Configure at boot time; Reconfigure at run
time
Default value: 512
Minimum value: 0
Maximum value: number-of-members-required-for-quorum*512
cfs_dvdfs_mount_limit
Clusterwide limit on the number of DVDFS filesystems that can be
mounted in the cluster. You must ensure that this attribute has the
same value on all cluster members.
As members leave the cluster, the number of filesystems capable of
being simultaneously mounted in the cluster will decrease, thus
potentially causing the inability of a filesystem to failover. As a
result, if you do modify the cfs_dvdfs_mount_limit value, it should
reflect the number of members required for the cluster to have quorum.
For example, if there are two members are required for the cluster to
have quorum, then the value of this attribute should not exceed 1024
(2*512). This value may additionally be limited by the memory
resources on a given cluster member, so that often a lower value may be
required for failover to be possible.
Supported operations: Query; Configure at boot time; Reconfigure at run
time
Default value: 512
Minimum value: 0
Maximum value: number-of-members-required-for-quorum*512
cfs_mfs_mount_limit
Clusterwide limit on the number of MFS filesystems that can be mounted
in the cluster. You must ensure that this attribute has the same value
on all cluster members.
Supported operations: Query; Configure at boot time; Reconfigure at run
time
Default value: 512
Minimum value: 0
Maximum recommended value: number-of-members-required-for-quorum*512
cfs_nfs_mount_limit
Clusterwide limit on the number of NFS filesystems that can be mounted
in the cluster. You must ensure that this attribute has the same value
on all cluster members.
Supported operations: Query; Configure at boot time; Reconfigure at run
time
Default value: 8192 as of Version 5.1B; 2048 for prior versions
Minimum value: 0
Maximum recommended value: number-of-members-required-for-quorum*8192
cfs_ufs_mount_limit
Clusterwide limit on the number of UFS filesystems that can be mounted
in the cluster. You must ensure that this attribute has the same value
on all cluster members.
As members leave the cluster, the number of filesystems capable of
being simultaneously mounted in the cluster will decrease, thus
potentially causing the inability of a filesystem to failover. As a
result, if you do modify the cfs_ufs_mount_limit value, it should
reflect the number of members required for the cluster to have quorum.
For example, if there are two members are required for the cluster to
have quorum, then the value of this attribute should not exceed 1024
(2*512). This value may additionally be limited by the memory
resources on a given cluster member, so that often a lower value may be
required for failover to be possible.
Supported operations: Query; Configure at boot time; Reconfigure at run
time
Default value: 512
Minimum value: 0
Maximum value: number-of-members-required-for-quorum*512
