今天在某客戶環境下分析某節點驅逐的故障，發現有安裝TFA，所以使用一鍵收集包含故障時刻的日志
tfactl diagcollect -from "2020-08-14 03:00:00" -to "2020-08-14 05:00:00" -all
結果收集日志時報錯空間不足：
Not enough space in Repository or TFA_BASE to run collections
實際df查看對應目錄的空間充足，這實際上是受限TFA repository的Maximum Size (MB) 設置，默認一般是10GB，客戶的環境由於保存osw時間過長，導致已超出這個大小，進而使收集日志報錯空間不足。
根據MOS文檔：TFA Diagcollection Reports "Not enough space in Repository or TFA_BASE to run collections" (Doc ID 2300038.1)
有明確的解決方案：
- tfactl set reposizeMB=10240
- tfactl print repository
Notably, The repository location can be changed using tfactl set repositorydir=
根據MOS的方案，我們查看當前值，結合實際情況設置為合適的值，注意需要使用root用戶操作:
tfactl print repository
tfactl set reposizeMB=20480
甚至在極端場景下，目錄空間不夠，可以設置其他有空間剩余的目錄：
mkdir /tmp/repository
tfactl set repositorydir=/tmp/repository
再次嘗試TFA快速收集相關日志：
tfactl diagcollect -from "2020-08-14 03:00:00" -to "2020-08-14 05:00:00" -all
可以成功收集所需日志：
[root@db01 grid]# tfactl diagcollect -from "2020-08-14 03:00:00" -to "2020-08-14 05:00:00" -all
The -all switch is being deprecated as collection of all components is the default behavior. TFA will continue to collect all components.

我這里是測試環境演示，沒什么太多信息所以日志比較小，實際生產環境，這個壓縮文件一般會大一些。
