10

Percentage, 1-100, 0 to disable. How quickly the health processor consolidates object segments after ingest. Increase this value (such as to 25, to consolidate over 4 HP cycles) to make new content readable sooner by clients. For multipart uploads via S3 clients, 10 is recommended; for SwarmFS, 100 is recommended, with extra space allowances for trapped space. Consolidation changes the ETag (which affects If-Match requests) and Castor-System-Version headers, but Content-MD5 and Castor-System-CompositeMD5 headers are unchanged. Therefore, have clients use hash and last-modified date, rather than ETag, to find if an object has changed.

A comma-separated list of headers that specifies the search order in which to find the host of an SCSP request. RFC 7230 5.4 requires a Host header with every SCSP request to support web servers or server farms that host multiple domains. Your client might use an HTTP proxy that modifies the Host header, but the Swarm domain name matches the original Host header. In that case, an HTTP proxy copies the original Host header into another header, typically X-Forwarded-Host.
Examples:
['X-Forwarded-Host', 'Host', 'X-ProxyForward-Host']
['Host']

scsp.enableVolumeRedirects

100

Issue a CRITICAL log message if the number synchronous indexing failures per hour exceeds this value. 0 disables.

scsp.synchronousListingWait

1.0

The length of time to wait for a list synchronization.

scsp.validateOnRead
SNMP: scspValidateOnRead

false

Disabled by default. Enable to force Swarm to validate the object's contents before returning successful read responses to client requests. Although validation can be specified on a per-read basis, this setting forces all reads to use validation. During the read from the disk, the content hash is computed. If the hash is wrong, indicating logical disk corruption, the socket will be closed before the last block is transmitted, forcing an error to the client. Note that using this option creates additional CPU load on the node.

List of OIDs to be skipped on output. To protect cluster performance, this setting causes the snmpwalk of the entire CASTOR MIB to skip several large, detailed tables in SNMP groups. The default list of OIDs causes a top-level snmpwalk to skip the groups or tables under clusterConfig, responseHistogramTable, hp, clusterdata, indexer, configVariableTable, castorFeeds, feedVolTable, performance, and recoveryTable. You can add or remove OIDs to control which sections of the MIB are returned by an snmpwalk. Enter values as strings in numeric form, relative to the Castor OID, .1.3.6.1.4.1.24659.1.

1048576

In bytes. The size of the multicast UDP socket read buffer. This value is capped the Linux /proc/sys/net/core/rmem_max value, which may be set via sysctl.coreRMemMax.

disk.defragBufferBytes

0

Size in bytes of the per-disk buffer allocated for bulk defragmentation operations. Disable bulk mode by setting to 0.

disk.defragUntilPercentage

0.8

Ratio, 0.0-1.0. The portion of known unused space that, when untrapped, will stop the disk defrag process.

disk.enableMultipath

false

[deprecated] Whether to enable support for Device Mapper Multipathing (DM-Multipath). Multipath support was dropped in Swarm 10.0.

disk.enableSSDTrims

false

Whether to enable trims on SSDs to potentially increase their life span.

disk.encryptNewVolumes

false

Whether to encrypt new Swarm volumes. Enabling encryptNewVolumes means that any newly-formatted Swarm volume will be encrypted

disk.encryptionCipher

aes-xts-plain64

The encryption cipher to be used when setting encryption for new Swarm volumes. Supported values are aes-xts-plain64 and aes-cbc-essiv

disk.encryptionHash

sha512

The encryption hash algorithm to be used when setting encryption for new Swarm volumes. Supported values are sha256 and sha512.

disk.encryptionIterationTime

5000

In seconds. The maximum amount of time to be spent while iterating to generate an internal LUKS key from a Swarm encryption key, which will be used when setting encryption for new Swarm volumes.

disk.encryptionKeyPrimary

The mnemonic name of the encryption key to use for encrypting new Swarm volumes. Do not use quotes. For this key to be used, disk.encryptNewVolumes must be set to True.
Example:
cluster_key_5_15_2016

disk.encryptionKeySize

512

The size of the internal LUKS key to be used when setting encryption for new Swarm volumes. Supported values are 128, 256, and 512.

disk.encryptionKeys

{}

A comma-separated list of mnemonic name and encryption key pairs, used for accessing encrypted Swarm volumes.
Example:
{'cluster_key_5_15_2016': 'a24f8ec391ab3341', 'cluster_key_5_12_2015': 'de3498245ce8bf89'}

disk.encryptionType

luks

The encrypted volume format type used when formatting new volumes. Supported values are: 'luks', 'luks1', 'luks2'.

disk.ioErrorToRetire

2

Count. How many consecutive I/O errors (no more than disk.ioErrorWindow seconds between each error) that will force a volume to retire.

disk.ioErrorTolerance

200

Count. How many I/O errors are tolerated, past which the volume is taken offline immediately. Swarm then marks the volume as Unavailable and initiates both the volume recovery process (FVR) and the erasure coding recovery process (ECR) to relocate all the volume's objects.

disk.ioErrorWindow

172800

In seconds; defaults to 2 days. The length of time after which an I/O error is forgotten, if no other errors followed and the volume's state is OK. Works with disk.ioErrorToRetire to control when volumes are retired. The default values means that if more than one error occurs within 2 days, the volume is retired.

disk.minGB

64

How many GB a device must have to be eligible for automatic storage volume assignment with volumes = all. Set to 0 to include all disk devices.

disk.smudgesToRetire

4

How many soft errors (smudges) over the life of a volume will trigger Swarm to retire the volume. A soft error occurs when the health processor does not get the expected data when validating the object but the disk gave no explicit I/O (hard) error. Set to 0 to disable the automatic retire.

disk.standbyTimeout

360

In seconds. How long until an idle disk spins down automatically.

disk.trappedToTotalPercentage

0.0001

Ratio, 0.0-0.01. The portion, of trapped space to total space, below which, will stop the defrag process (0.0 for no limit).

disk.volumes
SNMP: vols

Required. Specifies the volume storage devices for Swarm to use. Valid entries: all, or a space-separated list of Linux volume identifiers, such as /dev/sda, /dev/sdb. all (recommended) is required for hot plugging and lets Swarm to use all volumes larger than disk.minGB. If a node is shut down longer than disk.obsoleteTimeout, all of its volumes are stale and cannot be used unless you force a volume remount by adding the :k (keep) policy option modifier. To specify the size, add a modifier with units: vols1:100m vols2:250g.
Examples:
all
/dev/sda /dev/sdb

ec.inProgressConsolidationTimeout

86400

Time in seconds, 0 to disable. An 'in progress' multipart PATCH complete cannot be consolidated before this timeout.

feeds.maxMem

100000

In bytes. The maximum memory allowed per feed, for queue management.

health.startDelay
SNMP: hpStartDelay

900

In seconds; defaults to 900 seconds (15 minutes). How long after a node starts up to begin Health Processor checking and recovery processes. This option creates a grace period for the remaining nodes to stabilize in the cluster, which is useful in situations in which an entire cluster must be shut down and restarted.

license.url

<Swarm default 2T license>

The location and name of the Swarm license file, caringo/license.txt. Can be a pathname or a URL. To use the default 2 TB license, you must keep the default location.
Example:
http://10.10.15.32/config/swarm-license.txt

mdns.readBufferSize

1048576

In bytes. The size of the read buffer for the multicast UDP socket.

network.gateway
SNMP: gateway

Optional. The default gateway IP address in the subnet. Ignored unless network.ipAddress is set.
Example:

network.ipAddress
SNMP: ipaddress

The single static IP address for a node to use, or blank to use DHCP.
Example:
10.10.12.1

network.iptablesFileUrl

Optional. Location (URL) of Linux firewall rules to apply. When specified, Swarm transmits the rules without validation to the 'iptables-restore' command before starting the storage node processes.
Example:
http://10.10.15.32/config/swarm-iptables

network.netmask
SNMP: netmask

Optional. Sets the IP network mask for a node. Ignored unless network.ipAddress is set.
Examples:
255.255.255.0
255.255.0.0

network.timeSource
SNMP: timeSource

Recommended. List of one or more NTP servers by IP address or by name if network.dnsServers is set. You must have at least one usable NTP server in order for the storage node to start. If you don't assign a value here, a list from *.pool.ntp.org will be generated.
Examples:
10.20.30.55 10.20.30.65
0.be.pool.ntp.org 1.be.pool.ntp.org

node.subcluster
SNMP: subcluster

default

Specifies the name of the subcluster to which the chassis belongs. Names can have no more than 16 characters and no special characters, such as quotes and hyphens.
