conf

Path to a ceph.conf file. This is used to initialize the Ceph context for autodiscovery of monitor addresses and auth secrets. The default is to use the standard search path for ceph.conf files.

mount_timeout

int (seconds), Default: 60

ms_mode=<legacy|crc|secure|prefer-crc|prefer-secure>

Set the connection mode that the client uses for transport. The available modes are:

mon_addr

Monitor address of the cluster in the form of ip_address[:port]

fsid

Cluster FSID. This can be found using ceph fsid command.

secret

secret key for use with CephX. This option is insecure because it exposes the secret on the command line. To avoid this, use the secretfile option.

secretfile

path to file containing the secret key to use with CephX

recover_session=<no|clean>

Set auto reconnect mode in the case where the client is blocklisted. The available modes are no and clean. The default is no.

command

fs=<fs-name> Specify the non-default file system to be mounted, when using the old syntax.

command

mds_namespace=<fs-name> A synonym of "fs=" (Deprecated).

cap_release_safety

int, Default: calculated

caps_wanted_delay_max

int, cap release delay, Default: 60

caps_wanted_delay_min

int, cap release delay, Default: 5

dirstat

funky cat dirname for stats, Default: off

nodirstat

no funky cat dirname for stats

ip

my ip

noasyncreaddir

no dcache readdir

nocrc

no data crc on writes

noshare

create a new client instance, instead of sharing an existing instance of a client mounting the same cluster

osdkeepalive

int, Default: 5

osd_idle_ttl

int (seconds), Default: 60

rasize

int (bytes), max readahead. Default: 8388608 (8192*1024)

rbytes

Report the recursive size of the directory contents for st_size on directories. Default: off

norbytes

Do not report the recursive size of the directory contents for st_size on directories.

readdir_max_bytes

int, Default: 524288 (512*1024)

readdir_max_entries

int, Default: 1024

rsize

int (bytes), max read size. Default: 16777216 (16*1024*1024)

snapdirname

string, set the name of the hidden snapdir. Default: .snap

write_congestion_kb

int (kb), max writeback in flight. scale with available memory. Default: calculated from available memory

wsize

int (bytes), max write size. Default: 16777216 (16*1024*1024) (writeback uses smaller of wsize and stripe unit)

wsync

Execute all namespace operations synchronously. This ensures that the namespace operation will only complete after receiving a reply from the MDS. This is the default.

nowsync

Allow the client to do namespace operations asynchronously. When this option is enabled, a namespace operation may complete before the MDS replies, if it has sufficient capabilities to do so.

crush_location=x

Specify the location of the client in terms of CRUSH hierarchy (since 5.8). This is a set of key-value pairs separated from each other by '|', with keys separated from values by ':'. Note that '|' may need to be quoted or escaped to avoid it being interpreted as a pipe by the shell. The key is the bucket type name (e.g. rack, datacenter or region with default bucket types) and the value is the bucket name. For example, to indicate that the client is local to rack "myrack", data center "mydc" and region "myregion":

crush_location=rack:myrack|datacenter:mydc|region:myregion

Each key-value pair stands on its own: "myrack" doesn't need to reside in "mydc", which in turn doesn't need to reside in "myregion". The location is not a path to the root of the hierarchy but rather a set of nodes that are matched independently. "Multipath" locations are supported, so it is possible to indicate locality for multiple parallel hierarchies:

crush_location=rack:myrack1|rack:myrack2|datacenter:mydc
