@jaredbusch said in MongoDB Storage Engine Error Detected MMapV1 and wiredTiger: @scottalanmiller okay, they totally fucked this up. Yeah, this is some weird stuff.

Have you followed the ElasticSearch snapshot guide here? If so, where are you running into problems?

@scottalanmiller said in Remove Duplicate Entries from MongDB Collection: You can add an index as well, to avoid having duplicates occur in the future: db.myCollection.createIndex({"my_field_to_be_unique":1},{unique:true}) Good idea.

For more detail, showing the UIDs of each of the duplicates in question, try this little extension: db.myCollection.aggregate([ {$group: { _id: "$field_to_search", "dups": { "$push": "$_id" }, count: { $sum: 1}}}, {$match: { count: { $gt: 1 }}}])

Gotta love that MongoDB

@scottalanmiller said in Why Does Everyone Still Focus on Relational Databases?: I just built out a NoSQL ElasticSearch three node cluster in the lab. Whoo! The perfect DB setup for storing a hit counter for the number of times I've watched Tombstone!

@scottalanmiller said in Installing MongoDB 3.2 on CentOS 7: Just tested and deployed to CentOS 7.2 on Linode. This failed me, so I went to the mongo docs and the baseurl contains the variable $releasever. using that results in redhat//mongodb in the file, which is why I assume you hard coded that bit. Escaping the $ fixes it. cat > /etc/yum.repos.d/mongodb-org-3.2.repo <<EOF [mongodb-org-3.2] name=MongoDB Repository baseurl=https://repo.mongodb.org/yum/redhat/\$releasever/mongodb-org/3.2/x86_64/ gpgcheck=1 enabled=1 gpgkey=https://www.mongodb.org/static/pgp/server-3.2.asc EOF

A year later and no one posts. Just came across this today. Did not realize that Rackspace has added a Redis and MongoDB product! http://objectrocket.com/
