- Specify timeout in seconds for which file/directory attributes are cached. Should not be set along with -o rozofsattrtimeoutms.
- -o rozofsattrtimeoutms=N
- Specify timeout in milliseconds for which file/directory attributes are cached. This parameter is ignored if rozofsattrtimeout is also set.
- -o rozofsattrdirtimeoutms=N
- Specify timeout in milliseconds for which directory attributes are cached. When the option is not set,the timer value is the one specified either in rozofsattrtimeout or rozofsattrtimeoutms.

- Specify timeout in seconds for which name lookups will be cached. Should not be set along with -o rozofsentrytimeoutms.
- -o rozofsentrytimeoutms=N
- Specify timeout in milliseconds for which name lookups will be cached. This parameter is ignored if rozofsentrytimeout is also set.
- -o rozofsentrydirtimeoutms=N
