铁威马教程丨我的存储池容量增加后，却无法为卷增加容量?
本帖最后由 小铁1 于 2024-9-30 10:44 编辑故障排除适用机型 所有 TNAS型号适用版本 TOS 4.1.x & TOS 4.2.x & TOS 5.x请按照以下说明解决此问题:
[*]登录 ssh终端
[*]如果您已为卷创建了Hyper Cache，请在执行以下命令之前先删除Hyper Cache。
[*]修改存储池和卷
以下所有示例基于“MD0, VG0, LV0”（对应“阵列、存储池、卷”）您的“阵列、存储池、卷” 可能不是 “md0, vg0, lv0”， 请执行以下指令进行确认:<div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif">代码： 全选</font></font></font></font></div><div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif">lsblk</font></font></font></font></div>
让我们开始修改存储设置。请逐条执行以下指令：TOS 4.1.x & TOS 4.2.x：<div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif">代码： 全选</font></font></font></font></div><div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif">[</font></font></font></font><span style="font-family: Helvetica, arial, freesans, clean, sans-serif; color: rgb(51, 51, 51);">root@TNAS-???? ~]# cd /</span></div><div align="left"><span style="font-family: Helvetica, arial, freesans, clean, sans-serif; color: rgb(51, 51, 51);"># mdadm --grow /dev/md0 --size=max</span></div><div align="left"><span style="font-family: Helvetica, arial, freesans, clean, sans-serif; color: rgb(51, 51, 51);"># umount /mnt/md0</span></div><div align="left"><span style="font-family: Helvetica, arial, freesans, clean, sans-serif; color: rgb(51, 51, 51);"># umount /home</span></div><div align="left"><span style="font-family: Helvetica, arial, freesans, clean, sans-serif; color: rgb(51, 51, 51);"># vgchange -an vg0</span></div><div align="left"><span style="font-family: Helvetica, arial, freesans, clean, sans-serif; color: rgb(51, 51, 51);"># pvresize /dev/md0</span></div><div align="left"><span style="font-family: Helvetica, arial, freesans, clean, sans-serif; color: rgb(51, 51, 51);"># vgchange -ay vg0</span></div><div align="left"><span style="font-family: Helvetica, arial, freesans, clean, sans-serif; color: rgb(51, 51, 51);"># lvextend -l +100%FREE /dev/vg0/lv0</span></div>
TOS 5.x：<div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif">代码： 全选</font></font></font></font></div><div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif"># cd /</font></font></font></font></div><div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif"># mdadm --grow /dev/md0 --size=max</font></font></font></font></div><div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif"># umount /Volume1</font></font></font></font></div><div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif"># umount /home</font></font></font></font></div><div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif">[</font></font></font></font><span style="font-family: Helvetica, arial, freesans, clean, sans-serif; color: rgb(51, 51, 51);">root@TNAS-???? ~]# vgchange -an vg0</span></div><div align="left"><span style="font-family: Helvetica, arial, freesans, clean, sans-serif; color: rgb(51, 51, 51);"># pvresize /dev/md0</span></div><div align="left"><span style="font-family: Helvetica, arial, freesans, clean, sans-serif; color: rgb(51, 51, 51);"># vgchange -ay vg0</span></div><div align="left"><span style="font-family: Helvetica, arial, freesans, clean, sans-serif; color: rgb(51, 51, 51);"># lvextend -l +100%FREE /dev/vg0/lv0</span></div>
若提示“Target is busy”，请参考此以下操作指引解除其他进程对卷的占用,并取消 SSD 缓存,然后再次执行以上指令。TOS 4.1.x & TOS 4.2.x：<div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif">代码： 全选</font></font></font></font></div><div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif">fuser -mk /mnt/md0</font></font></font></font></div>
TOS 5.x：<div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif">代码： 全选</font></font></font></font></div><div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif">fuser -mk /Volume1</font></font></font></font></div>
注意：执行该命令后，SSH连接可能会自动终止。请再次通过SSH登录至NAS。
[*]调整文件系统大小
首先需要知道调整的卷的文件系统类型(btrfs/ext4)，执行以下指令进行确认:<div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif">代码： 全选</font></font></font></font></div><div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif">blkid /dev/vg0/lv0</font></font></font></font></div>
根据上一步得知的文件系统类型，选择要执行的指令:btrfs<div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif">代码： 全选</font></font></font></font></div><div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif"># /etc/tos/script/mntdata</font></font></font></font></div><div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif"># btrfs filesystem resize max /mnt/md0</font></font></font></font></div>
您会看到存储值缓慢增加。 约几十秒后，该过程将完成。ext4<div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif">代码： 全选</font></font></font></font></div><div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif"># resize2fs /dev/vg0/lv0</font></font></font></font></div>
您会看到存储值缓慢增加。 约几十秒后，该过程将完成。然后执行以下指令：<div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif">代码： 全选</font></font></font></font></div><div align="left"><font color="rgb(0, 0, 0)"><font color="rgb(51, 51, 51)"><font style="background-color:rgb(255, 255, 255)"><font face="Helvetica, arial, freesans, clean, sans-serif"># /etc/tos/script/mntdata</font></font></font></font></div>
