JAGag40401: cannot sleep during interrupt
• What is the problem? In some stress situation where the system is
under heavy IO load, if some nodes fail (TOCs), CVM resyncs the
mirrored shared volumes for the surviving nodes. While CVM is
resync'ing the volumes, it might invoke sleep(). If this sleep() is
invoked during an interrupt context, the system performs a TOC.
• What is the workaround? There is no workaround.
JAGag45544: Open fails for the device /dev/vxfen, after removing
and reinstalling a Serviceguard Cluster File System (SG CFS)
bundle.
• What is the problem? After removing a SG CFS bundle and later
re-installing the same SG CFS bundle on the same system, the
cfscluster config command fails to join the cluster and causes the
node to TOC. The following error is reported in the SG CFS pkg.log
file:
/sbin/vxfen-startup (exit=1) VXFEN vxfenconfig ERROR
V-11-2-1002 Open failed for device: /dev/vxfen with error 2
This is because the /dev/vxfen and /dev/vxfend devices are not
created after the bundle is re-installed, causing the SG-CFS-pkg to
fail. After the node is rebooted, /dev/vxfen and /dev/vxfend are
created as part of the reboot process.
This problem impacts the following SG CFS bundles: T2775xx,
T2776xx, T2777xx, T2795xx, T2796xx, and T2797xx.
• What is the workaround? After removing and re-installing the SG
CFS bundle, reboot the system manually.
