Ans: ‘/etc/exports’ is the main configuration file that … Hard Mount: A Hard mount is generally used for block resources like a local disk or SAN. It is actually quite hard to measure; assuming a non-congested, functioning network. Soft mount is an option that is very useful for mounting network filesystems say nfs filesystem so that soft mount will allow automatic unmount if the filesystem is idle for a specified time period Eg. The client uses the nfstimeout option value to determine how long to wait for an NFS system call to respond before timing out; this setting applies to hard and soft mounts. Call T & L today to learn more! When a program or application requests a file from the NFS filesystem, NFS client daemons will try to retrieve the data from the NFS server. We will see the difference between hard mount and soft mount. Hard Mount Point : if the client unable to communicate with the server then it will hang it, 1)NFS daemon repeately contact the server. It makes sure the no data is lost even if the server is not reachable for some time. These installation options define how the NFS client should handle NFS server crashes or failures. 3 4 5.

The nfs mount can be mount as a “soft mount” or as a “hard mount” these mount option define the how the nfs client should be handle nfs crash/failure.We will see the difference between hard mount and soft mount. Hard links and soft links are both pointers, in a sense. Top Answer. Hard mounts guarantee that a write over NFS will succeed (eventually). These mount options define how the NFS client should handle NFS server crash/failure. So, to get TCP, just add tcp to the NFS mount options. The default is 0 seconds. CIFS vs NFS – Difference : CIFS and NFS are the primary file systems used in NAS storage. The nfs mount can be mount as a “soft mount” or as a “hard mount” these mount option define the how the nfs client should be handle nfs crash/failure. Q:8 What is the difference between Hard mount & Soft mount in nfs ? The difference is that a soft link stores a textual representation of the file system path to the target, while a hard link (since it's just a directory entry) just stores the inode nubmer of the target, which must therefore be on the same filesystem as the directory the link itself is in. On the other hand, autofs only mounts nfs shares when they are needed and accessed. Either to use "mount" command or "net use" command would totally depend upon the type of network share that you would be mounting and would not make any difference if the enviroment is load balanced or not. 1) Soft/hard.

Hard Mount vs Soft Mount in NFS with Example 1) Soft Mount Output at the end. If the soft option is used, then the mount fails after retrans retransmissions have been sent. When a program or application requests a file from the NFS filesystem, NFS client daemons will try to retrieve the data from the NFS server. To most users, there is virtually no difference between the two except that if "intr" is not added as a mount option with hard nfs mounts, it will literally retry reaching the nfs server forever, where soft mounts will time out and stop trying if the nfs server is not reachable. A hard nfs mount; once the gateway is connected to the file system it is more of a “hard connection”, meaning that the gateway or server will continue to attempt to reconnect if the file system is unreachable. NFS also allows us to control the size of data chunks we send back and forth to the server. Whether you hard- or soft-mount a volume depends partly on taste but also on the type of information you want to access from a volume. The default is 0 seconds. A hard mount is generally used for block resources like a local disk or SAN.

Hard mounts can be, and very often are, used with autofs as well. This NFS mount can be done in either as a “soft mount” or as a “hard mount”. A soft mount is usually used for network file protocols like NFS or CIFS. A hard mount; once the gateway is connected to the file system it is more of a “hard connection”, meaning that the gateway or server will continue to attempt to reconnect if the file system is unreachable.
