現在，某サーバーはRaspberry Pi 4 Model B (RPi4) 4GB RAMで，Slackware ARM (32bit版)を動かしています．<\/p>\n\n\n\n

サービス内容は表向きにはWEB (https)のみで，メール (MTAとIMAPサーバー)，AFP, SAMBAなどプライベート用のデーモンがいくつか稼働しています．<\/p>\n\n\n\n

RPi4はもう一台持っていて，サーバーのハードウエアが故障した時の予備的な意味もありますが，RPi4がどれだけworkstation (WS)として使い物になるかの評価に使用してきました．<\/p>\n\n\n\n

今年のはじめにRaspberry Pi 5 Model B (RPi5)を中国から買って，WSの評価用はこちらを使うようになりました1<\/a><\/sup>まだRPi5は技適を取得してなく技適マークがついていませんからWi-FiとBluetoothの使用は控えています😅<\/span>．<\/p>\n\n\n\n

ということでこれまでWSの評価用に使用していたRPi4が1台浮いて，懸案のサーバーのソフトをRaspberry Pi OS (RPiOS) 64bitに切り替える作業に着手することにしました．ちょうど1TBのSSDも1台浮いています．<\/p>\n\n\n\n

それでRPiOSの64bit Lite版（GUIなし）をダウンロードしてマイクロSDカードにコピーして起動し，ひととおり設定してからSDの内容をSSDにコピーしてcmdline.txtと\/etc\/fstabの内容を書き換えたらブートしました．<\/p>\n\n\n\n

早速kde-plasma-desktopのインストールを仕掛けて昼食を摂り戻ってみるとファイルシステム関係のエラーがどっと出てシステムは無応答になっていました．<\/p>\n\n\n\n

SSDにUSB経由で供給できる電流が足りずにdisconnectしてしまったと推測されます2<\/a><\/sup>これまでも何度かやってます😅<\/span>．<\/p>\n\n\n\n

これ，5V5Aの電源に繋いでいるRPi5では起こらないです．RPi4にもRPi5用の5V5Aの電源を繋いでいますが，USBへ供給可能な電流は増えないようです．<\/p>\n\n\n\n

WorkarroundはUSB-HUBをRPi4とSSDの間に入れることですが，これだけは浮いているのがないんです😅<\/p>\n\n\n\n

テストのためにUSB-HUBを買うべきか，いっそもう1台RPi5を買ってしまおうか迷っています．<\/p>\n","protected":false},"excerpt":{"rendered":"
