Hi All, I''d like to ask about whether there is a method to enforce a certain txg commit frequency on ZFS. I''m doing a large amount of video streaming from a storage pool while also slowly continuously writing a constant volume of data to it (using a normal file descriptor, *not* in O_SYNC). When reading volume goes over a certain threshold (and average pool load over ~...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I would like to know the blocksize of a particular file. I know the blocksize for a particular file is decided at creation time, in fuction of the write size done and the recordsize property of the dataset. How can I access that information?. Some zdb magic?. - -- Jesus Cea Avion _/_/ _/_/_/ _/_/_/ jcea at

I was asked by a coworker about recovering destroyed datasets on ZFS - and whether it is possible at all? As a related question, if a filesystem dataset was recursively destroyed along with all its snapshots, is there some means to at least find some pointers whether it existed at all? I remember "zpool import -D" can be used to import whole destroyed pools. But crawling around the

I recently had an X86 system (running Nexenta Elatte, if that matters -- b101 kernel, I think) suffer hardware failure and refuse to boot. I''ve migrated the disks into a SPARC system (b115) in an attempt to bring the data back online while I see about repairing the former system. However, I''m having some trouble with the import process: hydra# zpool import pool: tank id:

For the encryption functionality in the ZFS filesystem we use AES in CCM or GCM mode at the block level to provide confidentiality and authentication. There is also a SHA256 checksum per block (of the ciphertext) that forms a Merkle tree of all the blocks in the pool. Note that I have to store the full IV in the block. A block here is a ZFS block which is any power of two from 512 bytes to
