PowerStore appliances connected to SupportAssist may experience an issue where the SupportAssist database (db) grows too large. This may result in space issues on one of the internal partitions (/cyc_node), which can interfere with the ability to perform upgrades or lead to a node reboot. This issue may occur on clusters that have an unusually large number of alerts, which causes the db to become too large. Attempts to upgrade the PowerStoreOS fail with an error suggesting that there is not enough space on /cyc_node to proceed with the upgrade.
SupportAssist creates a database entry for every file that is uploaded to SupportAssist, and does not have a mechanism for aging those entries out. If the system generates many alerts, the database can grow quickly. Example command outputs: [SVC:service@*******-* ~]$ df -hT /cyc_node Filesystem Type Size Used Avail Use% Mounted on /dev/md106 ext4 738M 497M 189M 73% /cyc_node And [SVC:service@*******-* ~]$ ls -lh /cyc_node/service/eve/hostmnt_config/opt/ese/var/run/ese/ese.db -rw-r--r-- 1 1100 1001 200M Sep 21 21:04 /cyc_node/service/eve/hostmnt_config/opt/ese/var/run/ese/ese.db
If you receive a similar error when trying to upgrade, disable SupportAssist on the PowerStore Manager user interface, wait 15 minutes, and then reenable it again. After these actions, the ese.db is re-created from scratch. If this does not resolve the issue, contact Dell Technical Support or your Authorized Service Representative, and quote this knowledge base article ID. This issue is resolved in PowerStoreOS 3.2.1.0.
