This article was found on the internet… I haven’t tried it.. but will consider it on a test copy of one of the ISE servers.\u00a0 Our issue that the drives are too small and logs occasionally have to get cleared by a manual process till we have time to migrate to a new larger disk install (per Cisco TAC).\u00a0 If it works on ISE 2.1 I’ll let you know!<\/p>\n
(original article below)<\/em><\/p>\n I had an issue with my NFR version of ISE which has a small partition (65GB). This soon filled to beyond 70%, causing backups to fail. I’ve devised a non-destructive method to expand the size of ISE’s data partition to 200GB (Cisco’s recommendation).<\/p>\n In my case, I was keen not to lose the licensing & configurations.<\/p>\n Procedure below – in case it’s helpful to anyone else.<\/p>\n Note – I take no responsibility if you wreck your ISE installation. This requires a certain level of Linux expertise – so please take care.<\/p>\n General One solution is to simply create a new ISE installation and do a system restore from the last backup. The problem with this, is the licenses aren’t restored, or you may not have a recent backup file to work with.<\/p>\n Solution At this point my donor VM has a permanent license for 20 nodes, but won\u2019t backup and will soon fail given the disk consumption. The target VM has a 90 day trial license which isn\u2019t helpful for our lab work.<\/p>\n At this point, power off both ISE VMs so we can work on their respective disks.<\/p>\n We need a Linux VM (e.g. Centos 6 – 64bit). We are going to attach the ISE VM disks to the Linux host and copy some data between the donor and target ISE disks.<\/p>\n The Linux VM also needs to be powered off to attach the ISE disks.<\/p>\n Use vSphere client to add two disks to the Linux VM \u2013 browse to the donor and target ISE VMs and bring in their respective disks. The donor is Disk 2 and the target is Disk 3.<\/p>\n Now boot up the Linux VM with its newly attached disks.<\/p>\n If we issue an fdisk -l we\u2019ll see the Linux native disks and the two ISE disks, note the size differences between disk 2 (sdb) and disk 3 (sdc):<\/p>\n [root@centos6-64 ~]# fdisk -l<\/p>\n Disk \/dev\/sda: 17.2 GB, 17179869184 bytes<\/p>\n Device Boot Start End Blocks Id System Disk \/dev\/sdb: 68.7 GB, 68719476736 bytes<\/p>\n Device Boot Start End Blocks Id System Disk \/dev\/sdc: 214.7 GB, 214748364800 bytes<\/p>\n Device Boot Start End Blocks Id System On both disks, the first partition (sdb1 and sdc1) is the boot partition \u2013 we aren\u2019t going to make any changes to this.<\/p>\n We need to copy data from partitions 2, 3, 6 & 7 from the donor to the target. Partition 7 is the most important \u2013 that\u2019s where our data, license and configurations are.<\/p>\n Now let\u2019s create some mount points so we can access the data on the ISE disks. On our Linux VM use the following:<\/p>\n cd \/mnt mount \/dev\/sdb2 sdb2 mount \/dev\/sdc2 sdc2 We can delete all the data on the target VM since we don\u2019t need these files on the above partitions. However, as mentioned above, we need to retain the 1st partition which is \/boot. In our case, this is \/dev\/sdc1 \u2013 leave this alone \u2013 any messing with this and your new target VM won\u2019t boot.<\/p>\n BECARFUL WITH THE FOLLOWING \u2013 ENSURE YOU\u2019RE NOT REMOVING DATA FROM YOUR DONOR DISK.<\/p>\n rm \u2013rf sdc2\/* Now check the partitions are empty on the target. If any files remain, delete manually, for example:<\/p>\n [root@centos6-64 sdc6]# ls -al [root@centos6-64 sdc6]# rm -rf .ICE-unix\/ .oracle\/ .tt_4024<\/p>\n Once the target partitions are empty, we\u2019re ready to copy the files from our donor ISE disk. Do this one partition at a time by changing directory into the donor partition and using cpio to copy the files from the donor to the target disk.<\/p>\n cd sdb2\/ cd ..\/sdb3 cd ..\/sdb6 cd ..\/sdb7 That\u2019s it!! Now power-off the Linux VM and remove the ISE disks from its inventory.<\/p>\n Boot up the new ISE VM. Everything should be intact: license, configurations, but now with plenty of free disk space.<\/p>\n ise1\/admin# sh disks<\/p>\n disk repository: 2% used (170852 of 14877092)<\/p>\n Internal filesystems: ise1\/admin# show udi<\/p>\n SPID: ISE-VM-K9 This article was found on the internet… I haven’t tried it.. but will consider it on a test copy of one of the ISE servers.\u00a0 Our issue that the drives are too small and logs occasionally have to get cleared by a manual process till we have time to migrate to a new larger disk … Read more<\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[9,11],"tags":[],"class_list":["post-17","post","type-post","status-publish","format-standard","hentry","category-cisco","category-linux"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tech.my-netsol.com\/index.php?rest_route=\/wp\/v2\/posts\/17","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tech.my-netsol.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tech.my-netsol.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tech.my-netsol.com\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/tech.my-netsol.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=17"}],"version-history":[{"count":0,"href":"https:\/\/tech.my-netsol.com\/index.php?rest_route=\/wp\/v2\/posts\/17\/revisions"}],"wp:attachment":[{"href":"https:\/\/tech.my-netsol.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=17"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tech.my-netsol.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=17"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tech.my-netsol.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=17"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
\nThe NFR version of ISE has a small partition size of approx 65GB. This quickly fills up to 70% causing backup jobs to fail. From this point, we\u2019ll call the old (smaller) version of ISE the donor VM.<\/p>\n
\nThe solution is to create a new ISE VM. We\u2019ll call this the target VM with a large partition (200GB). Bring the target VM up to the same patch level as the donor VM. In my case, this is 1.2 patch 2. Don\u2019t do any further configurations on the target VM.<\/p>\n
