So after recovering a box which had a controller failure we needed to mount the old fs to recover some stuff. when trying to mount /dev/sdc2 we got: mount: unknown filesystem type ‘LVM2_member’ fix is easy : modprobe dm-mod vgchange -ay lvscan now yields: ACTIVE '/dev/VolGroup/lv_root' [50.00 GiB] inherit ACTIVE '/dev/VolGroup/lv_home' [178.46 GiB] inherit ACTIVE…
While elastic search is usually run as a cluster, for the sake of this tutorial I am showing the _snapshot and _restore tools. mkdir /mnt/backups/my_backup chmod 777 -R /mnt/backups/ Must available on all nodes. curl -XPUT 'http://localhost:9200/_snapshot/my_backup' -d '{ "type": "fs", "settings": { "location": "/mnt/backups/my_backup", "compress": true } }' [root@centos-base mnt]# curl -XGET 'http://localhost:9200/_snapshot/my_backup?pretty'…

After installing elastic search it is useful for testing and training to load some sample data. 1) create mapping : curl -XPUT http://localhost:9200/shakespeare -d ' { "mappings" : { "_default_" : { "properties" : { "speaker" : {"type": "string", "index" : "not_analyzed" }, "play_name" : {"type": "string", "index" : "not_analyzed" }, "line_id" : { "type"…
While adding a new disk to an ESX5.5. box it could not finish the partitioning stage and did not add to the Datastores. Apparently ESX does succeed to clean up the Disk from the GUI. NOTE: This procedure will destroy all data on the disk
Simply pipe through python -m json.tool e.g. curl -u Administrator:kpassword http://172.16.3.136:8091//pools/default | python -m json.tool
