ROCKPro64 is single board computer (SBC) equipped with a PCIe x4 open ended slot. I'm planing to replace my Buffalo NAS mother board, and reuse the Buffalo NAS case.
According to compatibility list, ROCKPro64 supports 6 ports SATA card, Ziyituod SATA Card ASM 1062+1093 6-Port.
But I purchased one 10 ports SATA card, 10port 4x 1xJMB575 + 1xASM1166.

Many days headache was fixed this morning...
The problem with iCloud on my newly installed MacOS, which is High Sierra, 10.13.6, out of support by Apple.
The machine was installed via Internet, and the MacOS was Mountain Lion, then upgraded to High Sierra, the lastest can be installed in this 2011 iMac.
When connecting to iCloud at beginning, the iCloud can not sync Keychains, it is quite an issue for me, because I need to register all credentials to this iMac separately.
Then I decided to reconfigure iCloud by re-login to iCloud again.
But iCloud could not be registered any more after logout, I thought it could be issue with my unsupported OS.
The symptom was repeating asking for iCloud user and password, no matter which iCloud I like to use. In the email account list, the account is just appear in very short period, then closed immediately.
This morning I tried to send email, found out that I could not add iCloud account, I decided to search solution in Internet.
The solution works for delete all files related to iCloud and system configuration. It is works for my newly configured iMac, because I have nothing in it.
Run following commands in terminal
rm ~/Library/Application Support/iCloud
rm ~/Library/Preferences/com.apple.systempreferences.plist01
rm ~/Library/KeychainsThen reboot
sudo rebootWhen using vi editor in Synology SSH session, the ACL changed upon saving. This causes issue for permission sensitive application, such as SSH.
The vi command creates a new file, and write new contents into that file, and the new file doesn't follow the ACL of original file.
If SSH is not available, for example, the permission authorized_keys changed, and only public key access was opened. If the file was shared, GUI is allowed to change ACL in user's home directory.
The ACL page can be accessed using following steps.
PropertiesPermission TabIn Synology, use following command to check file ACL
/usr/syno/bin/synoacltool -get <PATH>To remove ACL, using following command
/usr/syno/bin/synoacltool -del <PATH>For example, remove @users group from usbshare1
/usr/syno/sbin/synoshare --setuser usbshare1 RW - "@users"More options can be found using following command
/usr/syno/bin/synoacltool -h
