SQL Server docker container with NFS mount as volume mapping -


i trying run sql server on ubuntu docker container using stranded microsoft/mssql-server-linux:latest docker image. data persistence mapping volume host (having ext4 file system) container using -v option in docker run command below 

docker run -it -e 'accept_eula=y' -e 'sa_password=######' -p 1433:1433                 -v /var/opt/database:/var/opt/mssql/data microsoft/mssql-server-linux

container running fine , able connect database. not want store data on host because of growing size of database , swarm reasons. thought run nfs server on other machine , mount nfs directory onto docker host , use nfs dir on volume mapping volume mapping 

-v /var/nfs/database:/var/opt/mssql/data

where /var/nfs/database nfs mount dir on docker host. when start container following error

2017-08-18 10:15:53.98 spid5s fcb::open failed: not open file /var/opt/mssql/data/master.mdf file number 1. os error: 87(the parameter incorrect.). 2017-08-18 10:15:53.98 spid5s error: 5120, severity: 16, state: 101. 2017-08-18 10:15:53.98 spid5s unable open physical file "/var/opt/mssql/data/master.mdf". operating system error 87: "87(the parameter incorrect.)". 2017-08-18 10:15:54.13 spid5s error: 17204, severity: 16, state: 1. 2017-08-18 10:15:54.13 spid5s fcb::open failed: not open file /var/opt/mssql/data/mastlog.ldf file number 2. os error: 87(the parameter incorrect.). 2017-08-18 10:15:54.13 spid5s error: 5120, severity: 16, state: 101. 2017-08-18 10:15:54.13 spid5s unable open physical file "/var/opt/mssql/data/mastlog.ldf". operating system error 87: "87(the parameter incorrect.)".

i have given permissions database files. below nfs mount snippet

sharedstorageip:/var/nfs nfs4 443g 47g 375g 11% /var/nfs

the release notes explain can't this:

hosting database files on nfs server not supported in release. includes using nfs shared disk failover clustering databases on non-clustered instances. working on enabling nfs server support in upcoming releases.

hosting database files on networked path not trivial, given demands database has reliability. hosting files on smb shares wasn't possible until version 2.2 of protocol.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
