New Features Introduced: server-side clone and copy, application I/O advise, sparse files, space reservation, application data block (ADB), labeled NFS with sec_label that accommodates any MAC security system, and two new operations for pNFS (LAYOUTERROR and LAYOUTSTATS). NFS v2 limits the file transfer to 2GB.Īdvancements in NFS v4 v4.1 and v4.2 NFS v4 NFS v3 and V4 can handle any amount of filesize in practical, it all depends on the client.

64 bit offset is even larger than 16TB size. However due to bug, its limit is set to 2GB.Ħ4 bitsize can handle files larger than 2GB. NFSv3 includes READDIRPLUS operation, which helps to get directory listing with file attributes in one go – a major performance improvement.ģ2 bit value limits to 4GB files. Parallel NFS is a new feature introduced in NFS v4 which starts the transfer multi-threaded and increases the speed. In NFS v4, this separate protocol is removed and this functionality in inherited into the main NFS package. Network Lock Manager was required in NFS v2 and V3 to lock a file over NFS and make changes. In NFS v4, we can create a single pseudo filesystem containing all shares from that particular server. It increased the speed of transaction.Īll exports can be mounted together in a directory tree structure as part of a pseudo-filesystem However with NFS v4 all calls can be sent as a single command and also executed in one go. NFS v2 & v3 used to send separate RPC call for each transaction on wire.For example:- a lookup, open, read, write, and close all operations are sent separately in different RPC calls. Efficient caching can be done in V4 and useful in concurrent transactions by updating user in case someone else changed the file during the same time. NFS v2 and V3 works on UDP, hence stateless. However by default UDP is used on NFS v2, and v3 and TCP is used in NFS v4. Hence kerberos is recommended for security. Difference between NFS v2, v3 and v4Īuth_sys is traditional authentication mechanim and used to send uid and gid is plain text which can be read in network. + They should really step up their game to attract more costumers and not disappoint them.In this post we will look at the differences between NFS v2, v3, v4 and the subversions of V4 i.e.

+ TNAS can be really annoying and not so professional + Always make a system configuration backup before updating

Nfs 4.1 encryption update#

This time I saved the system configuration just in case the problem happens again! After trying to update again, everything works just fine! After initializing the system, I can decrypt the encrypted folders normally again! Unfortunately, I did not have a system backup, so I had to installed the Apps and Backups again! After setting everything up, I wanted to try the new version again just for fun. I installed the older version back manually (4.1.27). But then after it was successfully decrypted using the authorized user's password, the contents (subfolders) say it is encrypted.

However, it can be encrypted using the password of the user authorized to that folder. I had the same issue today! After I upgraded to the new version (4.1.30) the encrypted folders did not work anymore!! The strange part I encountered is that the encrypted forder cannot be opened using the key.
