similar to: [cryptography] rolling hashes, EDC/ECC vs MAC/MIC, etc.

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

Hi, after a flaky 8-drive Linux RAID10 just shredded about 2 TByte worth of my data at home (conveniently just before I could make a backup) I''ve decided to both go full redundancy as well as all zfs at home. A couple questions: is there a way to make WD20EFRX (2 TByte, 4k sectors) and WD200FYPS (4k internally, reported as 512 Bytes?) work well together on a current OpenIndiana? Which

R users- In moving from R 2.0.0 to R 2.1.0 in Windows, I have encountered a problem with the "riwish" command in the package "MCMCpack". I've searched the documentation and can't seem to figure it out. For example: Define a matrix: > lam <- matrix(c(.00233,-.00057,-.00057,.00190),2,2) and then use the riwish command to generate a random inverse-Wishart

As a napp-it user who recently needs to upgrade from NexentaCore I recently saw "preferred for OpenIndiana live but running under Illumian, NexentaCore and Solaris 11 (Express)" as a system recommendation for napp-it. I wonder about the future of OpenIndiana and Illumian, which fork is likely to see the most continued development, in your opinion? Thanks.

I have a Dell R710 which has been flaky for some time. It crashes about once per week. I have literally replaced every piece of hardware in it, and reinstalled Sol 10u9 fresh and clean. I am wondering if other people out there are using Dell hardware, with what degree of success, and in what configuration? The failure seems to be related to the perc 6i. For some period around the time

Anyone here using http://www.sonnettech.com/product/tempossd.html with a zfs-capable OS? Is e.g. OpenIndiana supported? Thanks.

This might be a stupid question, but here goes... Would adding, say, 4 4 or 8gb usb keys as a zil make enough of a difference for writes on an iscsi shared vol? I am finding reads are not too bad (40is mb/s over gige on 2 500gb drives stripped) but writes top out at about 10 and drop a lot lower... If I where to add a couple usb keys for zil, would it make a difference? Thanks. Sent from a

I've just ordered a Siemens Gigaset C450 IP cordless IP/DECT phone, given that it's supported by asterisk http://www.voipuser.org/review_41.html However, I see that a slightly better Gigaset S450 IP is available for only a slight price premium. Are there any user experiences with the S450 IP? -- Eugen* Leitl <a href="http://leitl.org">leitl</a> http://leitl.org

Sorry for an off-topic question, but anyone knows how to make network configuration (done with ifconfig/route add) sticky in nexenta core/napp-it? After reboot system reverts to 0.0.0.0 and doesn''t listen to /etc/defaultrouter Thanks.

Dear SavioRs, I am doing some research where characters in different microsoft fonts serve as experimental stimuli. Hence, in plot labels, I would like to display the characters in specific microsoft fonts. I have figured out how to display letters and numbers, but I am having trouble with symbols such as capital delta. Before I go further, I am using R 2.2.1 on Windows XP with everything

Are any of you using the Intel 320 as ZIL? It''s MLC based, but I understand its wear and performance characteristics can be bumped up significantly by increasing the overprovisioning to 20% (dropping usable capacity to 80%). Anyone have experience with this? Ray

https://github.com/kubevirt/containerized-data-importer/issues/1520 Hi Eric, We had a question from the Kubevirt team related to the above issue. The question is roughly if it's possible to calculate the checksum of an image as an nbdkit filter and/or in the qemu block layer. Supplemental #1: could qemu-img convert calculate a checksum as it goes along? Supplemental #2: could we detect

Hi!We''re trying to pinpoint our performance issues and we could use all the help to community can provide. We''re running the latest version of Nexenta on a pretty powerful machine (4x Xeon 7550, 256GB RAM, 12x 100GB Samsung SSDs for the cache, 50GB Samsung SSD for the ZIL, 10GbE on a dedicated switch, 11x pairs of 15K HDDs for the pool). We''re connecting a single Linux

CentoOS 7 python-cryptography package is at version 0.8.2 It has a build-requires for python-cryptography-vectors of the same version (but different source tarball apparently) There is no python-cryptography-vectors in CentOS 7 base or updates. There is one in EPEL but it is version 0.8 -=- If you relax the BuildRequires to just require python-cryptography-vectors then the build fails
