Hello again<\/p>\n
So today I started installing a few updates on one of my servers (centos 7) and had the following issue , I could not install the new kernel version because there was not enough disk space in \/boot to accommodate the new kernel , so I went about removing the old files, and solving this problem permanently , so first I installed yum-utils<\/p>\n
#yum install yum-utils<\/p>\n
Then I used the package-cleanup utility (handy python script , yay python!!! )\u00a0 that allows us to remove duplicate or orphaned packages.<\/p>\n
Here is an example<\/p>\n
#package-cleanup –oldkernels –count=2<\/p>\n
so what this does is that it removes old kernels and keeps only the last 2 .<\/p>\n
So this does what we want , which is to remove the older version of the kernel , however we might have this problem again in the future . Looking for a solution I have checked \/etc\/yum.conf and there we have the option<\/p>\n
installonly_limit=5<\/strong><\/p>\n according to Red Hat and their deployment guide present here<\/a><\/p>\n <\/p>\n So , I changed the yum.conf to read<\/p>\n installonly_limit=2<\/strong><\/p>\n There , we have avoided this problem.<\/p>\n Of course that this has an impact on how many old versions of the kernel you wish to keep , and I do recommend that you set this value taking into account your needs … but for me at this point I feel that 2 is enough .<\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" Hello again So today I started installing a few updates on one of my servers (centos 7) and had the following issue , I could not install the new kernel version because there was not enough disk space in \/boot to accommodate the new kernel , so I went about removing the old files, and … Continue reading Centos \/ Redhat Remove old kernel versions<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[6,60,16,22],"tags":[79,3,80],"wppr_data":{"cwp_meta_box_check":"No","cwp_rev_product_name":"","cwp_rev_product_image":"","cwp_image_link":"image","cwp_rev_price":""},"_links":{"self":[{"href":"https:\/\/ruimoreira.co.uk\/index.php?rest_route=\/wp\/v2\/posts\/160"}],"collection":[{"href":"https:\/\/ruimoreira.co.uk\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ruimoreira.co.uk\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ruimoreira.co.uk\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/ruimoreira.co.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=160"}],"version-history":[{"count":2,"href":"https:\/\/ruimoreira.co.uk\/index.php?rest_route=\/wp\/v2\/posts\/160\/revisions"}],"predecessor-version":[{"id":162,"href":"https:\/\/ruimoreira.co.uk\/index.php?rest_route=\/wp\/v2\/posts\/160\/revisions\/162"}],"wp:attachment":[{"href":"https:\/\/ruimoreira.co.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=160"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ruimoreira.co.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=160"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ruimoreira.co.uk\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=160"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}installonly_limit<\/code>=value<\/em><\/span><\/strong><\/p>\ninstallonlypkgs<\/code> directive.<\/div>\ninstallonlypkgs<\/code> directive include several different kernel packages, so be aware that changing the value of installonly_limit<\/code> will also affect the maximum number of installed versions of any single kernel package.
