wdt_ID Brief Description of Issue Brief Description of Fix Applicable Product Versions Affected (if known) Link to supplemental Support Article(s)
1 A XenServer 6.2 to 7.1 upgrade fails with "[Errno 28] No space left on device:'/tmp/backup-rORnXu/.xen-backup-partition'". Find the folders with high inode usage, check which folders have a high number of files e.g. temporary files, and then delete the files from each folder. https://support.citrix.com/article/CTX227290
2 When attempting to install XenTools you receive error "Your Tools ISO is on a broken SR, XenServer will attempt to fix it before proceeding. Do you wish to continue?". Within "xensource.log" is error "Storage_interface.Sr_not_attached". Search for stale/duplicate XenServer Tools Storage Repository by running command "xe sr-list name-label="XenServer Tools". If there are multiple entries, find each one with state "currently-attached (RO): false" and forget them. https://support.citrix.com/article/CTX220219
3 XenServer time is incorrect after changing the BIOS time. Make sure all XenServer hosts in the pool have identical NTP servrs specified. You may have to manually restart the "ntpd" service and then run a manual sync as explained in the CTX article. https://support.citrix.com/article/CTX226572
4 Virtual Machine cannot start with error "VDI is being used by another operation". Look for instances where the VBD is attached to other VMs as described in the CTX article. https://support.citrix.com/article/CTX214407
5 On some high resolution monitors, the XenServer console does not display. Use an alternative monitor or connect remotely via SSH for example and edit the grub config file to edit the VGA section, as outlined in the CTX article. https://support.citrix.com/article/CTX226191
6 You receive error "Internal error: Connection failed: no host resolved" when adding a new server to the pool. Reconnect XenCenter with the IP address of the pool master and then try again. https://support.citrix.com/article/CTX224728
7 Applying a patch through XenCenter results in error "invalid_file". Trying to patch via CLI hangs. This is caused by no SR being elected as the default SR. Right-click on an SR and set it as default. Citrix XenServer 7.1. https://support.citrix.com/article/CTX224142
8 After upgrading an HPSA driver XenServer can no longer boot. You see error "Kernel panic" on the XenServer console. Before upgrading the HPSA driver, add options "hpsa hpsa_allow_any=1" to "/etc/modprob.conf". https://support.citrix.com/article/CTX223518
9 When importing a VHD into XenCenter you receive error "No local storage and no default storage: cannot import Transfer VM" on the XenServer console. Set a default SR for the pool in XenServer and then reinstall the Transfer VM using the steps provided in CTX article. https://support.citrix.com/article/CTX215142
10 The Management Interface shows blank in the Nteworking tab on XenCenter and the pool Management Network bond shows as "unknown" after adding a host to the pool. Find and forget all NICs that are disconnected on both the master host and the host you just added. Citrix XenServer 7.1. https://support.citrix.com/article/CTX223314
